All you need is a saute' pan, some water, some butter and some good shake. Don't use high heat, just let it simmer for about 45 minutes while you constantly stir and mash. When its done, put the whole mess into a tall TupperWare container and put it into the freezer. The butter (with the THC) will rise to the top, the leaf will be in the middle and the water will turn to ice. Slightly warm the outside of the TupperWare container and slide the frozen contents out. Now take a sharp knife and seperate the oil layer from the rest. Throw the rest away. That's it.
