not a crock pot method, but stinkattic's washed butter recipe is the best and most versatile that i have tried. very little "weed" flavor and one hell of a kick @ recommened dosing.

try it. its pretty easy. just make sure you real carefull with transferring of hot stuff into cold jars and you'll be fine. BTW- i like to make 'buffalo canna-wings' with this butter. :eat:
