If you, like me, do not like to waste food, then you too has to think sometimes about recipes to use leftovers or byproducts. Such a byproduct is the spent grain, a leftover from our homebrewing. I added a part of it directly to a bread and dried the remaining spent grain overnight in the oven. I found this great idea on this site.
During the night a delicious malt odour filled our flat and spent grain was compeltely dry. Milling with my home mill was easy. I got a slightly coarse flour with a slightly sweet malt taste. Its taste reminds me strongly of roasted grain “coffee”. I think it will make a great substitution for bread and rolls or whole grain cookies or even for the dough of a quiche. And beeing figh fibere (50%) and high protein (23%) makes it a healthy substitution, too.
Another interesting point for me is the fact that 1.5 kg malt yields only 500g Spent Grain Flour. That means that about 1 kg starch is converted to sugar during the mashing process. Now that it does not amaze me any longer that the wurt was so sticky.
Spent Grain Flour
- Spend Grain
Distribute the spent grain over three baking trays and dry it in the oven at 60°C on convection mode. Leave the oven door open ajar.
Depending on the amount of spend grain it will take about 6 hours or longer to dry out completely.
Let the dried spent grain cool down and grind in a mill to flour.
