Every cook has a hero recipe, a failproof main that saves dinner time and again. For Sunny, that main is Oxtail Stew: it earns rave reviews, satisfies any comfort food craving and the slow braise is low-maintenance -- a welcome relief on busy workdays. Tonight's Puerto Rican menu has an exotic spin, too, with Kale-lloaloo and Sauteed Plantains -- que rico!
