a ratio of 1 ounce of weed to 1 pound of butter makes a good product, but it depends on the quality of weed.
step 1: remove large stems
step 2: use a blender, food processor or coffee grinder and grind, but do not overprocess or it will be hard to strain afterwards
step 3: heat butter in crock pot on low setting until crock pot is hot, then turn off. skim off the foam that rises to the top
step 4: repeat twice more, letting butter cool before reheating. this process gets rid of moisture in the butter (making clarified butter)
step 5: add weed, stir, heat on low, stirring occasionally for 1-2 hours
step 6: cool up to 8 hours and repeat heating/cooling process 2 more times. the butter will be thicker after the third heating
step 7: strain the butter into a large container and use when needed
