Cannabutter

Hello all i made canabutter with trim on stove for 3 hours at 170 degrees. Inused 3oz trim to 1.5 pound of pure butter. I strained it chilled it overnight and when i took it out of fridge to seperate from water i drained all water and the consistency of the butter was crumbly. Any ideas

Cooking with cannabis section, threads galore on butter and probably better directing your question there
