I've been looking at recipes for fondant. I didn't know there were so many variations. Some add vinegar,cream of tartar, or glycerin to a granulated sugar and water base. I ran across some that use powdered sugar instead of granulated, shortening or oil and were a no-boil version. My question is... are any of these additives bad for the bees? Are there some that would be better to use than others? I already know that I intend to add an herbal stimulant.
