Honestly dude, I really think you should take your questions about technical shit like that, to a more active forum, like the ones at www.grasscity.com
I used to think it was just a place that sold cool pipes, until i stopped dreaming about the bongs, and looked at the top bar of the site.

If you want a recipe, basically just take a couple 8ths and simmer it real low with butter for a couple of hours in a pan, and then just use that butter for the butter in the brownie mix. It might help to pour the butter int oa container nad let it sit overnight, but I haven't tried it yet. Also, be careful, b/c simmering it will stink up the fuckin house man.
