There was one time I put in 4 ounces to 4 sticks of butter; after was strained returned it to the crock pot tossed in another half stick butter and ADDED in 11 grams of bubble hash, waited 5 hours then unlike the first time, no straining, put in the freezer until solid and when removed from the water the hash stuck to the bottom of the butter. 3/6 people that tried that butter will never eat cannafood again. Long time medical patients too =/. Put it all on the double boiler mixed it up with a couple bars of hersheys chocolate and handed him a spoonful, he ate half of that spoonful.....That was the first time I had to sit and pray with a grown man and his wife, for 4 hours, I felt very very bad...Be careful....it can be traumatizing. - Friendly J
