I would say it's the shea butter. This needs to be heated to 170 degrees and held there for 15 min or so or you get crystals when it cools (grains) I usually heat mine first, get it to temp hold it there for about 15 min, stir occassionally- remove from heat and when it starts to cool, add beeswax- the cocoa butter will melt pretty quickly with any temp above 98 degrees or so. Let it all cool, you should have no troubles after that with grains. but as previously mentioned, do read the posts- they help tremendously.
