Aquafaba: What It Is and Why You Want It

And for heaven's sake, don't throw it away.  At least save it and give it to me.

Aquafaba is loosely defined as bean broth or bean water, the fluid that is drained off from a can of (previously) dry beans, not canned green beans. Vegans and other health food nut-types, as well as Depression-era survivors, will advocate saving this super nutritious liquid that the rest of us discard and using it to fortify soups and stews.   They wax poetic on how it "beefs up" soup and stews, imparting a meat-like flavor while being packed with protein and making a nutritious substitute for bone broth.  They even go so far as to say it makes a delicious soup all on its own.  (I suspect they've been eating their own vegan cooking for too long.)

However, when aquafaba is more strictly defined, it refers only to the broth from canned garbanzo beans, as known as chickpeas.  This is where things get interesting.

While straight from the can it makes a great binder, what is truly incredible to me is that it whips up and becomes foamy like an egg white.  I kid you not.  Just like an egg white.  The liquid from other beans will whip up to some extent, but none as well as garbanzo bean liquid does. [Update:  I reserved the liquid from canned white beans.  It didn't whip up quite so stiffly as the garbanzo bean liquid, but it was pretty good.  I used it to make chocolate mousse and it tastes just fine.  I'll be reserving this in the future as well.]

As with egg whites, both cream of tartar and sugar make a great stabilizer.  When it comes to stabilizing whipped egg whites used in baked goods, as experiments in America's Test Kitchen showed, cream of tartar is the hands-down winner for creating the fluffiest muffins and cakes.[1]

To measure aquafaba for use in baking, shake the can vigorously before opening, and then drain the beans using a wire strainer over a bowl.  Reserve the beans for another use, perhaps soup or hummus.  Whisk the aquafaba (because the starches that we can't see settle at the bottom) and then measure.  Any leftovers may be frozen in ice cube trays (for ease of use, freeze in 1 tablespoon portions), and then popped out and stored in freezer bags.  Previously frozen aquafaba whips up just as beautifully as fresh.[2]

For your information:
  • There is about 1/2 cup of liquid in a 15-oz can of garbanzo beans.
  • Experiments in America's Test Kitchen showed that the liquid of black beans did not whip up anywhere near as well as garbanzo bean aquafaba.  
  • Home- or commercially-canned garbanzo beans (15 ounces) will have about 1/2 teaspoon of salt added.  You may wish to take this into account in preparing baked goods and desserts.

The Importance of Preserving with Purpose in Mind

The late pandemic has prompted a phenomenal surge in the number of people who recognize a need to be better prepared for life's challenges.  In the forums I frequent, I read a lot of questions regarding the "best way to preserve/store xyz."  Dry storage of long-term staples like grains and beans, etc., has been covered in other posts.  Here we'll consider preservation methods for produce.
The best way to preserve different types of produce varies.

Personal preference:  The first important factor to consider is what you like, your personal preference.  What other people do is totally irrelevant.  For example, most directions for dehydrating pineapple indicate that it should be cut into chunks and then dehydrated.  Dutifully following the directions, I did that.  Unfortunately, we didn't really like the result.  The taste was fine, but we really didn't like the texture, even if I cut the pineapple into small chunks.  I was about to give up on dehydrating pineapple when I came across a suggestion to cut it into very thin slices.  That was exactly what we needed.  The pineapple looks like strips of fruit leather.  The texture is great.  We all love it. 


Intended use:  Sometimes the best way to preserve an item depends on how you are planning to use it.  For example, most gardeners find themselves with excess zucchini.  And most people shred it and throw it in the freezer.  This is probably the best way to go for making zucchini breads, cakes, and cookies--if you have the freezer space.  But what if you don't?  In this case, some people advocate dehydrating shredded zucchini.  It's great for adding to soups, but I don't like it in baked goods.  This is because zucchini doesn't quite fully rehydrate, and often the result in cakes and breads is a little on the chewy side.  However, if the zucchini shreds are canned (according to the directions in the Ball Blue Book or another accepted guide), they work very well in baked goods.

Another way we like to use zucchini is to dehydrate slices for soups.  One of our favorite uses is dehydrating 1/4" thick slices for making deep-fried zucchini later in the year. 

Berries get preserved in numerous ways.  The most important is a dozen or two pints of jam each year.  Fruit rolls are probably next on the list.  Raspberries are dehydrated whole for use in raspberry-lemon muffins.  If there are still berries left, then they are pureed, dehydrated, and powdered for adding to smoothies (which will have to be mixed by hand if there is no electricity, so having the berries powdered in advance helps here). 

Best texture.  If any produce is to be eventually used as a sauce, then it gets made into a sauce first, then dehydrated, and then powdered.  Sauces prepared this way will rehydrate to the smoothest consistency.  This is especially effective for tomato sauce.  And it's also nice because you can add just the amount you need without wasting the rest of the can. 

Beans have the best texture, and use the least amount of fuel, when they are pressure canned.  Beans can also be dehydrated, but then they kinda fall apart and separate when rehydrated.  The taste is fine, but the texture's a bit different.  It works for backpacking or emergency meals, but it's not what we really want to eat regularly.  I'll use them when I want taco salad without having to open up a quart jar just for me.  Garbanzo beans, on the other hand, are an entirely different matter.  Our favorite way to use them is to pressure can, puree, dehydrate, and then powder.  It sounds like a lot of work, but it's really not a big deal.  We love being able to just add water and have hummus dip ready in an instant.

Nine Medical Myths Busted

Bring Your Own Bandages:  Medicines and Supplies to Have on Hand Before Disaster Strikes is now available on Amazon.  Read the reviews and see for yourself.  Available in digital and hard copy.

Disclaimer.  I am not a licensed health practitioner.  This is just another post on knowledge and understanding you might wish to acquire in advance of a disaster in case no higher care is available.  As long as our society is functioning, you should leave anything more substantial than applying a Band-Aid to the professionals.  No medication, including those available over the counter, should be taken without consulting a physician.  Information shared here is for educational and entertainment purposes only.  It is not medical advice nor a substitute for licensed medical care. 

Myths abound when it comes to medicine.  It's important to know the facts, because if medication is withheld or tossed out due to a misconception, lives could be at stake.

People allergic to seafood are also allergic to iodine.  This one is important because, in a nuclear event, individuals may need to take potassium iodide tablets or paint povidone-iodine on their skin.  Iodine is also used to clean wounds and treat water.  But because some physicians have believed and perpetuated the iodine and seafood allergy myth, naturally some individuals allergic to seafood are concerned about using iodine.  But the myth is just a myth.  Iodine is perfectly safe for people with a seafood allergy to use.  If this myth is a concern for you, addresses for three articles that discuss this issue are included in the list below.[1, 2, 3] 

Expired tetracycline becomes toxic.  Myths get spread among medical professionals just like everyone else.  The myth of expired tetracycline becoming toxic is traced to an anecdotal report of one person developing renal failure, which was attributed to the use of outdated tetracycline.  The condition is called Fanconi's syndrome and can occur due to numerous causes.  That anecdotal case in 1963 spawned this myth.  Since that time tetracycline and all tetracycline-related antibiotics have been reformulated.  According to The Medical Letter, a professional newsletter,

"The only report of human toxicity that may have been caused by chemical or physical degradation of a pharmaceutical product is renal tubular damage that was associated with the use of degraded tetracycline... Current tetracycline preparations have been reformulated with different fillers to minimize degradation and are unlikely to have this effect" (The Medical Letter, Vol. 44, Issue 1142, 28 October 2002).[4, 5]

We'll DIY penicillin when our supply runs out.  Let's be honest here.  Yes, Alexander Fleming isolated and manufactured penicillin in 1928.  Perhaps that primitive technology isn't beyond the ability of trained microbiologists or chemists today.  But a sterile lab is essential.  And beyond that, what Alexander Fleming isolated was low-grade stuff.  It wasn't particularly strong, and the urine of the patients it was used on had to be collected and filtered and treated so that the penicillin could be reused.  And it takes a long time to make it.  And the DIY stuff has a super short shelf life.  You have to start it before the patient needs it and the patient could be dead before you're done.  Those are a lot of obstacles to overcome.

Hand sanitizer lasts forever.  No, it doesn't.  The alcohol evaporates.  And the alcohol is what kills bacteria and viruses.  When you reach the expiry date on hand sanitizer, it's time to toss the hand sanitizer or repurpose it. 

Hand sanitizer is as good as washing with soap and water.  This is most definitely not true.  Hand sanitizing should never be substituted for good washing with soap and water.  If washing is not an option, hand sanitizer should be applied generously to dirt- and debris-free hands and rubbed in vigorously for at least two minutes.  Four minutes would be better.  But keep in mind that some microbes are totally impervious to hand sanitizer.

Wounds must be cleaned out with a disinfectant.  All wounds should be irrigated copiously, and more especially so when antibiotics are in short supply and nutrition and immune responses may not be ideal.  However, the disinfectants that kill bacteria and viruses also kill living tissue, which then becomes dead tissue that may give rise to infection.  Disinfectants should only be used to clean around a wound, never in.  The exception is the use of benzalkonium chloride in treating any bite from an animal that could possibly have rabies.  All puncture wounds and bites should be irrigated with water (or BZK, if warranted) for 10 minutes with gentle pressure.

Using a tourniquet means amputation.  No, tourniquets are used all the time in operating rooms today.  However, even if it did mean amputation, it's better to lose a limb than a life.  Tourniquets are only used when 30 minutes of constant direct pressure (no peeking every five minutes to check) has failed to stop bleeding.

A lot of people allergic to penicillin will also be allergic to cephalosporins (i.e., Keflex).  The myth is that 10% of people allergic to penicillin will also have cross-reactivity to cephalosporins like Keflex.  The reality is that the number is less than 1%.[6]

Rubbing alcohol is an effective fever reducer.  Well, actually, that is true.  Applying rubbing alcohol to the skin will help reduce a fever.  It may also kill the patient, especially if the patient is young.   One of the basic tenets of medicine is to first, "Do no harm." And using rubbing alcohol to reduce a fever can most definitely be harmful. Remember, alcohol can poison the body by drinking, by absorption through the skin, or by inhaling the vapors. When alcohol is rubbed on the body to reduce a fever, that alcohol is absorbed into the body at a toxic level. The vapors are also inhaled by the patient. Using rubbing alcohol to lower a temperature was common practice through much of the last century. Unfortunately, the practice persists with some physicians, even with increasing numbers of cases of alcohol poisoning causing coma and death, especially in infants and small children.[7]

I'm sure there are many more medical myths out there.  Feel free to post them in the comments below.  As always, this information is just for your entertainment.  Use it only as a springboard for doing your own research.

The Minnesota Starvation Experiment

Food Storage Made Fabulous, the 2nd volume of articles from the Prep School Daily blog, is now available on Amazon.  With over 100 family-friendly recipes using basic long-term food storage staples, your family will have no idea there's a crisis. 

Do you know anyone who has ever dieted?  How fun are they to be around?  Have you or has anyone you know ever tried the intermittent fasting diet?  Now that is fun.  You eat normally five days per week, and for the other two days you get 500 calories for women or 600 for men.  I lost weight, but I hated diet days.  And even though I thought I was doing well with it, my family hated diet days because apparently I was cranky.  And that's when we all knew that the diet day would end at bedtime, and that if I really wanted to, I could go eat anyway.  What happens when there really isn't any more food, at least for that day's rations?


I don't know about all of history, but in recent history there have been conscientious objectors to war.  While some probably were just trying to avoid military service altogether, others truly wanted to serve their country but had an insurmountable objection to killing another human being.  Some of these men became ambulance drivers and medics.  A small group of others, men aged 22 to 33 years old, volunteered to participate in the Minnesota Starvation Experiment, conducted between November 1944 and December 1945.  Of the 400 men who volunteered, 100 were selected for personal interviews to identify suitability for the study.  Ultimately, 36 of the best and brightest were chosen--men with college education who exhibited the greatest levels of physical and emotional stability. 

The stated objective of the experiment was to simulate the effects that starvation resulting from the then-current war would have on the people of Europe and thus be able to determine the best ways to help them recover when hostilities ceased.  The volunteers were all healthy young men of military age.  During the first twelve weeks of the study, the men were carefully observed so that baseline psychological and physiological behaviors could be established.  They consumed an average of 3200 calories per day and were required to walk 22 miles per week, just over three miles per day.

The starvation phase lasted 24 weeks.  The men continued walking 22 miles per week, as refugees just might, and were given diets ranging from 1200 to 1800 calories per day.  The goal was to get the men to lose 25% of their original body weight.  They were fed twice per day with foods thought to be common to the starving populations of Europe--potatoes, rutabagas, dark bread, macaroni, and turnips, among other things.  The diet was very high in carbohydrates and low in protein.  And not only is it similar to what starving populations then were eating, it's also pretty similar to what a lot of people store now.

During the starvation phase, the men lost all interest in anything that didn't involve food.  They were hungry all the time.  Even just after they ate, they were still hungry.  They also reported a decrease tolerance to cold and needed extra blankets, even in the summer.  They were dizzy, extremely fatigued, and experienced muscle soreness, hair loss, and reduced coordination.  Some had to quit college because they could not concentrate. Most of the volunteers exhibited serious distress and depression. 

Of the thirty six volunteers who started the experiment, four were unable to finish for various reasons.  Two began stealing food to eat, including raw rutabagas, and were treated for psychiatric issues as well.

During the recovery phase, the goal was to get men back to their original weight.  The men were given varying amounts for their rehabilitative diets, from 400 to 1200 extra calories per day, to re-nourish them.  The volunteers still felt like they were starving. 

After the conclusion of the experiment, when the men could eat whatever they wanted, some were consuming up to 10,000 calories per day.  It was then that they regained their weight, and many gained up to 10% more.

When you store the minimum amounts recommended by members of the Church of Jesus Christ of Latter-day Saints, people who have advocated and studied food storage for over 150 years, you are storing about 2,000 calories per day.  That minimum does not work out well if you are doing heavy labor or are pregnant or even stressed.  Mental stress also demands a lot of calories.  If you've purchased one of those year's storage kits that touts 1,200 calories per day, do you think your family is really going to be happy?  Will you tell yourself that the crisis will end before the food runs out, so you eat it more quickly?

Maybe you should try out living on 1,200 calories a day to see how it goes.  Do it with the whole family.  Remember, those men in the experiment were volunteers and they knew the experiment would come to an end.  When the grid goes down, no one really knows when it will come back up.  How are you going to react when you are hungry.  All. The. Time?  Are you going to be patient with your family members? The men in the experiment became introverted.  They easily lost patience with one another over the most trivial of issues.  It won't be any different for us.

One of the interesting findings of the experiment was that the men needed over 4,000 calories per day to begin rebuilding their bodies, and it took them up to two years to do it. 

Maybe it's time to do a little more shopping and stocking.  There's no time like the present!

Lessons Learned from COVID-19 Quarantine and Food Supplies

In visiting with people prior to the shutdown, as the nouveau panic preppers were scrambling to purchase rice and beans or #10 cans of Mountain House, other people and I would mention the importance of eating what they normally eat, avoiding food fatigue by having a good variety in the diet, etc.  The normal stuff.  And we would routinely get dismissed with something along the lines of, "People will eat it if they are hungry enough."  I've decided to summarize some of their quarantine-diet observations below.

"I eat canned tuna regularly, but in February decided to get several dozen cans of X Chili, a favorite in my youth, because it boasted a lot of protein.  It was the first time in decades. It seemed to dehydrate me and left me drained and sluggish, even though I also had regular yogurt and vegetables.
It was basically thick beef tallow, and I didn't see much actual meat. If I had it to do over, I would have gotten actual meat.  This chili will ruin me."

"We used this quarantine as a test run to use up some old ABC and XYZ (major freeze-dried food companies) meals. We tired of it quickly and the salt was too much for my blood pressure. We're baking bread daily and I've been able to buy flour. When the quarantine ends, I'll start storing grains. We're eating a lot of eggs.  I should consider raising chickens. I stashed chocolate bars.  Those were popular and eaten quickly. Plans for this year's garden will focus on nutritionally dense foods."

"Same as the others have said. Too much sodium in the freeze-dried XYZ and ABC. We started adding rice, pasta, potatoes....  Sometimes added no-salt canned or frozen veggies.  We used the freeze-dried meals as starter or seasoning to supplement. Chocolate had to be rationed. We ate half of it in the first week.  Now it’s one piece on weekends. We are baking lots of bread, using natural yeast from our dried fruit stores.  We are eating a lot of eggs, twice as much as normal.  My supplies are lasting, but fresh is getting harder to come by. Local stores are still delivering but only about 25% of my order goes through."

"I think a lot of people are having the same experience. You summed it up nicely with 'Basically we used the freeze-dried meals as a starter or seasoning to supplement.' That is the way to go."

"XYZ tastes better but has too much salt. If we had to rely on them, I would cook rice then put 1/3 of a packet of XYZ on each plate to give it some flavor and add a piece of bread. Eating a whole pouch of either brand gets old fast.  The ABC would be more manageable for me due to the lower salt content. Stock both just to add some variety but look for other food options."

"I buy grain in bulk and then grind it fresh to maximize nutrition. A good electric grinder costs a small fortune but it pays for itself in a couple years. The bread tastes so good and is so filling it barely needs anything to go with it for a meal...a bit of peanut butter, hummus, cinnamon rolls, etc."

"The freeze-dried stuff has its place. When you are working hard you will likely do better with a little more salt. If not, then mix in some supplemental grains and stretch the flavors out a bit. Lack of salt can be a real problem with food, but having it along with other spices can make the difference between fatigue or lack of it."

Now for what people were glad they had stored:
Yeast
Salt pork
Evaporated milk
Pancake mix and maple syrup
Toilet paper
Oatmeal
Beef jerky
Coffee
Canned fruit
Cooking oil
Bacon grease
Pasta

And what they wish they had stored, or stored more of:
Bacon
Powdered eggs
Non-fish canned meats
Cleaning supplies
Hand sanitizer
More variety in ready-to-eat meals.  "I'm tired of Chef Boyardee, I'm running out of canned soup, and everything else needs prep work."
Lactose pills 
Onions
Milk
Cheese
Shelf-stable whipping cream

There is a Chinese curse that goes something like this:  "May you live in interesting times."  I think we've been Chinese-cursed and others are beginning to wake up to the fact.  There are reports from around the country of people starting to stockpile food and supplies again in the event that a second wave, as they are calling it, materializes.   I have no idea what's coming; I can only make guesses just like everyone else.  We can learn from what people panic-purchased and what they were glad to have gotten, and what they wish they had more of and prepare accordingly.

Our times are indeed interesting at present, and I fully anticipate that we have a lot more interesting experiences to pass through.  Now's the time to prep while the prepping is good.
