I take dried leaves/trim/little popcorn buds-- just cut off any stems on the leaves. Put yer butter in the crock pot and then mash as much green stuff as you can down into it. Keep it on low, and keep an eye on it so it doesn't bubble a whole shit ton, and stir it around every 10 minutes or so. When the green has mushed down into the melted butter, add more butter and more green- as much green as you can get in there. Keep going til you don't have anything else green to put in, or your crockpot is full. I leave mine a good four hours or so, gradually adding more butter and green as I go, and make sure the last bunch has at least an hour or so in the crockpot. Then strain off the plant stuff-- press down on it to get all the buttery goo you can. That part really helps to have a strainer with handles that fits over your sink and an extra set of hands. Let the butter cool- I pour mine into a 9x13 cake pan, and when it's not insanely hot, pop it into the freezer. I like the 9x13 because it's a lot easier to cut it into sticks that are butter sized and shaped. For discretions sake, I wrap it back up in the butter wrappers, put it all into the butter box and freeze it that way.
