I wash cannabutter or coconut oil three times to help get rid of the smell in the oil. I also take 2lbs of butter, heat to 150 or so and only use the clarified butter that results. I toss all the milk solids....it tends to taste funny. I usually use 40 grams or so of the best pot I can find, the last batch was 900 per 1/4 lb. Thats about 200 more than usual, but miles better than usual. I made 70 cookies from 40 grams last batch....thats about .58 grams per cookie or about 112 mgs of THC per cookie. I also had great luck making caramels as well...you can hardy taste the maryjane in the treat. Also always use lecithin in the treats.....it gives a kick, hard, quick to the head, but its about 2/3 as long a buzz. The caramels had too much THC....about 175mg per caramel....two is too many!
