What are your favorite things to add to your M&P soap to jazz it up besides embeds? I know you can add a bit of butter and I have seen a recipe adding goat's milk or honey. Is there a good rule of how much you can add of, say, cocoa or mango butter, or liquids like soap? If you add those do you add a bit of beeswax or stearic acid to keep it firm? I know additives are usually done in small amounts - do they make a big difference? Inquiring minds want to know how to improve M&P :!:
