I got the basic recipe from a cookbook using nut flours. I've made it two different ways so far. I used flaxseeds instead of flaxseed meal once. That was an accident. The next time I did it, I did it correctly. I liked the seeds better though. This time I've doing it with the flaxseeds, and a tsp. of instant coffee and a tbs of cocoa. I have it in the oven now. I got the instant coffee and cocoa from a pumpernickel recipe but didn't use any other parts of the recipe.
I'm delighted with the crunch of the bread. I like spreading stuff on it. But I am trying for some sort of flavor. I don't know if the tsp and tbs amounts are enough, but that is what was called for in one loaf of the pumpernickel bread.
