I'm trying to make raspberry and tangerine donuts with whole grain. No finish. Trying to get the flavoring into the dough. When done I want the donut color the same as the flavor... tangerine is orange-ish, etc. Q: is using concentrated flavorings going to colorize the product as I want or should I color it some other way? I'm going to use albino wheat to let the color come through. Should this work? Where can I get potent fruit [liquid] flavorings in a store around Boston or my mail online?
