dry rather than wet. im not a fan of kief or hash butter. ive done all of the above lol and had a much lighter green color and significantly better tasting butter from dry trim and popcorn thats been quicky pulsed in a food processor. yes there is a bit of kief at the bottom of the processor but nothing significant. ive made hundreds of pounds of butter in the last 3 years as i own a commercial edible company.
