Found out why my butter tasted so bad--
I didn't clarify and convert it to ghee first...
------------------------------------------
"Making Ghee:
To make the Ghee, we melted unsalted butter and cooked it at low temperature, until the butter fats separated from the Ghee. We then skimmed off the floating butter fats, and sucked off the Ghee, using a turkey baster, leaving the heavier butter fats in the bottom of the pot.
Most recipes for extraction with butter call for boiling the material in water and butter, but we studiously avoid adding water and our Ghee extraction has only the lightest tinge of green and no chlorophyll flavor.
Here are the three extractions taken out of the refrigerator, where they were stored between cooking and actual pressing. Note that the butter, olive oil, and the coconut extractions have a slightest green tinge, yet none actually had a chlorophyll flavor."
