‘Ultrasonic espresso’ made with cold water and high-frequency sound waves uses less energy than the traditional version – and taste tests show it’s just as good.
A few months ago I saw a video of someone who used an ultrasonic cleaner to make extracts, so i tried it. I did 30 - 60 mins for each of orange peel, banana peel, pepper corn, anise, vanilla bean, cinnamon, and coffee. The coffee smelled absolutely disgusting, but this was like an hour rather than 3 mins. I had no idea how much time was appropriate. I also used vodka instead of water. Idk why I thought the coffee would work. The rest seem roughly what I’d expect. I’ve done traditional extracts previously. It makes sense to try water for coffee. I feel dumb for not trying that obvious combination.

sounds like the thought emporium?
