Use organic butter! Crock pot no good cause it's on a thermostat and turns on and off, also an electric stove. Best to bouble boil over constant low gas flame. I add water, simmer for 24 hours over double boiler, put in refrig to seperate water and butter, then take the brick of butter off the water layer.
My question: is the sludgy water left on the bottom high material. I throw it out.
Lemonboy, how old are u?
