Not knowing how to cook is like not knowing how to fuck. And not knowing how to simmer butter without burning it is like not knowing semen is going to shoot out of our dick.

But, for the uninitiated, a simple task:

Simmer 1/4 lb. butter with 15-30g of the good stuff (finely ground) for 30-45 minutes. Simmer means that it’s just at the point before boiling. If steam bubble are still forming, then it’s above a simmer. Next, strain it through cheesecloth (or T-shirt if you’re ghetto) into another container once it has been cooled enough to touch. Boom. Ganjabutter.

For something different, try happy booze.
Crumble dry weed into a bottle of alcohol (I like to use vodka). Keep the bottle in a warm dark place and shake it up daily. After 10 days, strain it through cheesecloth into another container, then make Green Russians.
