Thanks for the tips LapLap! I hadn't seen the Saran Wrap & pound approach or a meat grinder. Did you see the lo-fi method with pictures somewhere? I wouldn't want to make it too easy to do either, as it helps deter consumption frequency. Heh. It's like having a lot of junk food options right next to me vs a short walk. Some effort deters me from mindless consumption. My friend calls it "required activation energy".
I recently learned about the Spanish New Year grapes from Animal Crossing New Horizons
