My procedures have changed drastically over the years to the point I now use a Magical Butter machine. Very simple:
- Break apart 2 ounces of product (I use ~75% bud, 25% sugar leaf)
- Decarb product at 245F for 25 minutes in the oven
- Add 4 cups of coconut oil
- Add the prepared product
- Turn the machine on
I've also done it in a double boiler configuration, both with a crock pot, and on the stove. However, because the Magical Butter machine chops up the product periodically during its cycle, when I did it before the machine, I would grind the product up in a coffee grinder before I decarboxylated.
When we do an oil run, we do several runs as mentioned above all at the same time. Usually a half pound worth of product at a time.
