Piquillo peppers, descendants of Peru’s chile de arbol, require a long, hot, dry growing season, which fits Sonoma’s Dry Creek Valley to a T. Gardeners and farmers get their piquillo pepper seeds from the Chile Pepper Institute at New Mexico State University or online from Peppermania. Piquillos are not edible raw; instead, they’re smoke-roasted over wood and then packed in brine in jars or cans. If you grow piquillos, simply smoke-roast them until they’re done. Banana peppers are a good substitute for the piquillo peppers, too.
