Years ago, chef Dave Arnold expressed a desire for a substance that had the consistency, texture, and applicability of chocolate, but wasn't chocolate. He wanted to be able to coat food in ketchup as one coats, for example, cherries in chocolate. After some experimentation, he was successful. Here's his recipe:
1 kg de-odorized cocoa butter
325 g powdered tomato (spray dried or freeze dryed)
60 grams malt vinegar powder
25 grams salt
Spices to taste (onion powder, garlic powder, etc)
60 grams mycryo (to temper)
