Cannabutter

I decarbox it about 30 45 min on 230degrees grind it up real fine and then I double boil it with glass or metal bowl on top with 2 cups of water and 2 sticks of butter I boil for 3 to 4 hrs the longer the better. And I just use a super this strainer it's very thin made of rubbery plastic no cheesecloth for me lol and I drain super well and pour it in a bowl to let sit in freezer a hr and the butter hardens so I cant peel it off and dump the water. And vuala!!
