Just a few days ago I posted about bagels, now it’s bread. I know, it’s crazy. But winter time is time to bake a lot of warming, comforting things. And bread is definitely one of those, don’t you think?
Back in August I told you all about my friend Pete, and his home-brew supply store, Homebrews & Handgrenades. I told you all about how he gave me a ton of spent brewing grain to bake with, and I made that bread.
Well things have been a bit busy around here since then. I remodeled almost the entire place, had no appliances, and then there was Halloween, Thanksgiving, Christmas, etc. It hasn’t been conducive to insane recipe experimentation like is required when you get something brand new, like spent grain. So whatever I haven’t used yet is sitting in jars in my freezer, waiting for me to decide what to do.
What is spent grain?
Spent Grain is a byproduct from brewing process. The chemical composition of wet spent grains is given below:
- Water, 80%
- Protein, 5%
- N-free extract, 9%
- Fat, 2%
- Cellulose fibres, 4%
- Minerals, 1%
First, I dried out a bunch of the grain by laying it out on a cookie sheet and baking it at my oven’s lowest setting (170° F) for 7 hours or so, basically “overnight.” This was important because the grain was wet when I got it, and I froze it immediately. That means there was a lot of moisture trapped in there!
Once it was dried (and a little toasted, ’cause I raised the temperature a bit for the last hour), I let it cool completely. Then I used my KitchenAid grain mill attachment to grind it into a flour. I used a somewhat medium grind, it wasn’t too fine but not too coarse. And then- voila- I had spent grain flour! Which, by the way, you can store in your pantry in sealed container for as long as you like.
