I think I have a "b" next to my name or something? Anywho - it's my butter, AND cookie recipe. Not really hard at all, and a really good use of your medicine if you want it to last a long time.
I have actually (in the past) screened the plant for hash, and then used the screened bud for cooking cannibutter.
You can also use PVB (Pre-vaped Bud) in cooking.
It's like the boy scout/ girl guide method to making edibles. USE EVERYTHING.
Since you have a low tolerance, you would want to make your butter so that you are consuming 0.1-0.5 of a gram of bud, per "serving" or cookie. Best way - TEST. Go really small at first, like 1/4 cookie. Wait a couple hours, see how you feel - then, if you want - try more.

There are probably better ways - but this works for me, every time.
