oil is usually harder to screw up making lol. butter is pretty simple tho. heres a recipe i use and works wonders.
take a stick of butter to about 5g's of mids 3.5 of highs 1/4 of lows or like a half of shake/ trim
put in a double boiler melt butter add in ground up bud stir on med to lowish heat. for about 1hr you want the water to be lightly boiling
when its been about an hour take the inside pan put in fridge after 30 mins stir it up and let it set.overnite
then reboil it down and cook for 30 more mins. then strain and refrigerate and presto great butter that gets you perfectly high, not sickeningly high.
pm me if you got any more cookin questions.
