was watching a video on bubble hash early this AM. the way they went about it looked wasteful. most i have known used electric utensils to stir, and stirred much longer to avoid making 3 or 4 batches. product still looked tasty though... used to make primitive oil (40 years ago, still have glassware) using pure grain. it was "effective", but had more chlorophyll etc in it affecting the taste. VERY green..
