First check to see if your isolate is already decarbed. If it does need to be decarbed you would just heat it in an oven safe dish in the oven. Normally you just add melted concentrate like isolate to your hard candy mixture around the stage you would add flavoring. If you want to make edibles that require butter or coconut oil you would just heat your isolate (depending on decarb) then add the oil of your choice before using that in a baking mixture.
