Cannabutter
Cannabutter is butter that has been used to extract the active components from your herbs for use in cooking. The process works for ABV as well. The basic procedure is to heat the herbs or ABV together with butter, then strain. The temperature is extremely important and must be carefully controlled to avoid overheating and destroying the desired components.
If oil is used instead of butter, the result is called cannaoil.
