I do this when I make bread also. Thanks for the lard tip, I've been meaning to pick some up to make refried beans. For breads made with yeast, use bread flour. Completely changed my bread game. I've added ground pepper (pre ground, very fine, white too) garlic powder, chili powder, paprika, you name it. Pre ground, dry spices get mixed into the bread flour. Start with small amounts and experiment. Maybe, quarter/half teaspoons to start. I'll have to make a post sometime.
