Spent Grain! Your Newest Baking Buddy

What’s spent grain?! Why, you silly little thing, it’s grain that’s already been used for brewing! Let’s say you’re a home brewer and this is your thought process; “I’ve just made a delicious batch of stout, now I have all this grain left over WHAT AM I TO DO?!

Stop worrying your pretty little head, dear reader. The answer is Spent Grain Flour. Take all those yummy grains you just used for your beer, spread those suckers out in a single layer on a couple of sheet pans, set your oven to the lowest setting, and let them dry out over the course of a few hours. Once you’ve dried out your grains, just run them through a grain mill, milling them down as small as you can and VOILA! You’ve got yourself some Spent Grain Flour.

And because I am oh-so-wonderful, I’ve included here a recipe for delicious Spent Grain Brownies
