Do you have food grade cocoa butter than can be melted with other chocolatte

Yes

Yes and many big names to choose from

Not sure. Sorry

are you referring to cocoa butter for lip balm, lotions etc or are you referring to cacao butter? for cacao try walmart or amazon..

I looked this up online for you and they do sell Cocoa Butter at this particular Meijer but idk if it's what you're looking for.

You'll have to call the food department for the fondtain ingredients..
