Making any kind of edibles begins with decarbing the buds. 60 minutes at 240ºF in the oven is a good place to start.
From there, you infuse the butter/oil in the MB with the decarbed buds. 160ºF is the standard for that, and at least 4 hours would be the time setting. I run my oils for 8 hours and let it sit overnight, then do another 8 hours the next day. After I strain it and while it's hot, I add 1Tbs/cup of liquid sunflower lecithin (which makes it much easier for your body to absorb the THC). That mix goes in the fridge overnight, and the next day it's ready to make gummies/brownies/cookies.
This is the recipe I use:
Two 3oz boxes of regular Jello (with sugar!)
Three ¼oz packets of plain gelatin
1 cup cold water
1/4 cup light corn syrup
1/4 cup infused EVOO
And if you want to see a full description with pictures, you can
skip down to the middle of this post (the first half is how to decarb and infuse, which I've described above).
Here is another recipe as well.
