What I do is dry it out then jar like you would weed. Don't waist a long time curing it though as soon as it is dry you are fine. I put it in a ziplock bag and crush it up and then throw it in a crock pot. I make space cakes and I have NEVER had anyone complain, I eat 1/3 of a cookie and I am fucked for 6 hrs! LOL but I don't smoke alot, I only smoke about 1-2 bowls a day.
I add 20-24 grams of premo sugar leaves to each stick of non salted butter, put it in a crock pot on low for 22 hrs with enough water not to burn the butter or weed. Then strain it into a picture through cheese cloth and a strainer then chill till the butter gets hard. I just made some brownies from a Ghiardelli box, the double chocolate one and they were amazing! It asks you for 2/3 cup of oil, I called Ghiradelli and asked them if I could substitute the oil for the butter and they said yes just melt first. So what I did was run some water on the stove "not too hot" and I put a glass measuring cup in the water with butter in it till it melted. The box says bake at 325 but I kept it at 300 and used the easy brownie pan and it was done 5 min early.
My buddy gave one to a guy and told him to only eat half, he ate the whole thing and went to the Casino. Well he got so fucked he was scared to come out of the Casino! LOL he was hiding in there and his wife had to come get him out of there. On the way home he ate a whole pizza by himself and then wanted to make butter all the time instead of smoking! LOL Any questions feel free to PM me! GL brotha! Don't rush it!
Oh and the only time i have seen people recommend freezing is if you are going to make bubble hash.
