I'm interested in hearing whether or not chocolate makers who sell at fairs and festivals have had any success selling unsweetened baking chocolate. I love using my bean-to-bar chocolate in baking, of course, but would like to hear if vendors at these kinds of events have tried it. My thought is packaging it as four 2-oz bars with about four recipes included......basics like brownies, cookies, cake, etc.
The trick to using liquor instead of cocoa powder is to understand that liquor by weight is +/- 50% fat. You can't use liquor and not adjust the other fats that the recipe calls for (butter, vegetable oil, etc).
For example if your recipe calls for 1/4 c of cocoa powder, you need to use 1/2 c of liquor and reduce the other fat in your recipe by 1/4 c. it's really that simple.
I think you'll also find that by reducing other fats, your baked goods will be much lighter and fluffier than using shortenings, or oil. At least that's been my experience.
