I make my butter, really coconut oil, with water. Let it cool in the refridgerator, pour off the water, and then I remelt the hardened oil with fresh water, get it to near boiling and let it harden again, and remove the water a second time. This gets rid of a lot of the green chlorophyll color and taste. Then I do my decarb at 245°F for 20-25 minutes, when the bubbling stops.
