Oh man...
I recently made a shit ton of hard candies, also, airhead style candy, chocolate, fudge, and caramel.
I used a crockpot about 3/4 full of butter, then stuffed as much trim as I could into it, medium heat for three hours, strained and repeated 2 more times, stuffing the same butter with more trim each time. then strained again and boiled all the plant matter lightly and strained that as well to cool and later retrieve excess butter. I tell you the plant matter had as much or more butter still trapped than the hot liquid butter I was able to strain originally. Lightly boiling, straining, cooling and collecting is crucial for maximum yield.
Then just used half a cup of butter in each batch of candy. They turned out incredible. During the process I ended up tasting all the candy, and by the end of the day I was more medicated than ive ever been from edibles, or vaping...hmm, highest ever? Still have yet to have too intense of an experience though, but it was close..
