Chop the cacao butter into fine pieces to measure.
Fill a small saucepan with a few inches of water and bring it to a boil over high heat. Turn it off.
Place the cacao butter in a heat proof bowl, and place it directly over the boiling water, but not touching it.
Stir for 1-2 minutes until it begins to melt. At this point, make sure that no water or liquid gets in to the chocolate as it can cause the texture to get mealy!
