If you're willing to waste a little extra weed, then simmer it in butter until the butter is dark as shit and the weed is dust/ashes when you touch it.
Takes 20-45 minutes depending on how much you use.
Took me 15 minutes for 2 bowls worth.
I dipped some store bought cake in it and it tasted really good.

Didn't kick in until 3 hours while I was sleeping and suddenly I'm nearly tripping out while asleep lol! I woke up high and had a pretty good morning. It's probably because I used so little that it took long to hit.
