The main ingredient in many cannabis-infused edibles. This is an extract because the THC is extracted from the cannabis then infused with the butter. Cannabutter can replace butter in any recipe. If making your own cannabutter, always remember "low & slow". You will want infuse the butter over low heat for several hours, it should never reach a boil. The 'low & slow" process allows the THC to be fully activated without burning the herb. Another tip for the homemaker, always use unsalted butter, the higher the quality the better. Typically high quality butter has less water which in turn produces a larger yield.
