i like to use fresh semi dry trim and not grind it up. i add 1 lb butter to 3 oz. semi dry trim. melt butter in crock pot, fill half full of water then add trim. let simmer for at least 12 hours then strain with kitchen strainer pressing all liquid out then pour 2 or 3 cups of boiling water over trimmings and press again. let stand in the fridge over night. take butter from container and melt in large pan on stove then add 6 to 8 cups water and bring to a slow boil for 5 minutes and strain with cheese cloth and let that set over night in the fridge. most of the time this takes most of the seed and stem taste out. if you have a lot of green trim i some times melt and rinse for a 3rd time. this makes for an easy on the pallet butter that will get the job done with hardly any grainy texture.
