depends what u want idk. ive made one batch where i cooked the butter and water and shake in a crock pot then filtered it and re cooked it with some more hash. strongest butter ever!!
If u just want it to work id say like a 1.7grams would be good for one batch of cookies,brownies etc but if u have enough try using a 1/8th or a quarter .I was just talking to a friend yesterday about making 1 batch of brownies with like an ounce of hash,and splitting it 2 ways .theyed be the strongest ever almost lol
