I've always loved the smell of dried distillers grain. Last month I picked up a couple bags of pancake mix (made by Weisenberger) at Buffalo Trace that have some "Distiller's Four" mixed in. Looking at the ingredients list it looks like a fairly small amount is added to the mix.
The pancakes are quite tasty. The distiller's flour announces its presence in a subtle way. You get a faint smell and taste of being in the fermenting room.
Anyone know where I can get a bag of straight distillers flour? I'd like to add this to other things I cook as well.
