Momofuku's Roasted Brussels Sprouts

Brussels sprouts, trimmed and halved

grapeseed oil (preferred as it's neutral in flavor, but olive or canola is fine, too - I recommend picking some up because it's great to rub your cast iron pans down with, too)

fish sauce, plus more to taste (some brands are saltier than others - start here and add more if you like - I did)

water

rice wine vinegar

juice of 1 lime

granulated sugar

garlic clove, finely minced

to 3 red bird's-eye chiles, thinly sliced with seeds (I only had a jalapeño pepper, so I used two of these)
