Looks like this is an old post but hope this still helps. If by leaves you mean good trim leaves from the buds then about 2 oz per lb of butter (4 sticks) is a good amount. Just use the butter the recipe calls for. Then start with small portions to see the strength. It takes about an hour to feel the effects. If you eat too much it will make you sort of stoned and wired.
rudy2010 Reviewed by rudy2010 on . Cannabutter questions Made butter last night. Used 6.6oz of fine ground leaves, popcorn bud and sweet trimmings. I used 6 sticks of butter, the 1/2 cup sticks. Do those ratios sound about right? Ended up with about 1.5 cups of cannabutter. How much would you put in a batch of brownies? Rating: 5
