"What on earth is diastatic malt powder? How can it be a 'basic food
storage' item if I've never even heard of it? If I've never even heard
of it, do I really need it?"
Diastatic malt powder is usually produced from barley (only because barley is cheaper than wheat), and is added by mills to the bread flours they produce. It is used in baking breads to impart a natural sweetness, so you need a little less sugar or honey, and it makes crusts a little browner and shinier. On its own it has a bit of a bitter aftertaste (who actually goes around taste-testing bits of flour?), which is not noticed when mixed with other ingredients and baked.
However, diastatic malt powder is also made very easily with wheat. This, and because it helps make a better loaf of bread, qualifies it to be considered part of basic food storage.
So how does one go about making diastatic malt powder? Well, sit down. Get comfortable. This explanation is going to take all of about 60 seconds. That is, if English is your second language and you have to look up half the words. Otherwise, skip the sit down and get comfortable parts.
For detailed instructions on sprouting wheat, see here. If you're familiar with sprouting:
- Soak 1 cup of wheat for 6-12 hours.
- Drain and rinse and drain again.
- Rinse and drain every 6-8 hours (three times daily).
- Continue for 2-3 days until sprout roots are as long as the wheat berry.
At this point, spread the sprouted wheat on a baking sheet or a
dehydrator tray. Set the temperature to 110-120 degrees. (If the
temperature goes much above 125, you will produce non-diastatic
malt powder. The enzymes will be killed, and your powder will do
nothing to promote a better rise in your bread.) This will take about
eight hours. The sprouted wheat must be completely and thoroughly dry,
just like the wheat berries you started with.
At this point, it's time to grind the dried, sprouted berries. You can
run them through your grain grinder, but bear in mind, if your sprouted,
dried wheat is not completely and thoroughly dry, you will gum up your
mill. I prefer to use a blender just to be safe--and a regular cheap
blender-that-you-got-at-a-garage-sale-after-someone-else-got-it-at-Walmart
will work just fine. Coffee grinders also work.
Congratulations! You are now the proud parent of diastatic malt powder!
Store your diastatic malt powder in the refrigerator. (Just keep as cool as possible post-collapse.) Use within six months.
When you are making bread, replace 1 teaspoon of sugar with 1/2 to 1
teaspoon of diastatic malt powder. To do its job properly, the
diastatic malt powder must be mixed in with the yeast while it proofs.
Use only 1/2 to 1 teaspoon per loaf of bread or 3 cups of flour. Do not
use more, or your dough will become sticky and not rise as well.
How does diastatic malt powder work? The dried and powdered sprouted
wheat (or barley, but the barley must be whole grain--pearled barley
will not sprout) contains
enzymes that help break down starch into sugar, which the yeast then
feeds on. The active enzymes in diastatic malt promote full and
efficient growth of the yeast throughout the fermentation process,
helping the dough to be smoother and rise higher. It's especially
useful in doughs with a long rise or fermentation process.
