Is there a shelf life to colored cocoa butter and can colored cocoa butter go bad? Or does it just bloom? Is there any special way I should store it? thanks
It will absolutely oxidize. General principles for storage are the same as for chocolate - minimize exposure to heat, oxygen, and light. When it goes bad, you'll be able to taste it. It won't be dangerous, just won't have flavors you'll like. I recently had a container of Chef Rubber white butter turn on me.
