How to Make Ghee
I use a crockpot. Put the butter (up to eight pounds fits in mine) in, cover, and set the temperature setting to "low."
Let the butter melt and simmer for about eight hours; at this point, there will be a sort of foamy "scum" on top (protein, mostly), a lot of butterfat (all the good yellow stuff) in the middle, and the milk solids at the bottom.
