Brussel sprouts have the potential to be exquisite. These were incredibly simple. Hot oil, sprouts chopped in half, add to oil chopped half down. After a bit, put a lid on. Add a bit of water if needed to get the pan juices. Sprinkle with flakes of fine sea salt.
Cooked this way they get a sort of sweetness. Broth could be added instead of water. If you have no objection, I recommend trying this with duck fat, but butter and vegetable oils– including coconut oil– work as well. You can have it going while you cook something else. If only brussel sprouts were not so expensive!
