This incredibly quick and easy dish from New Orleans chef Donald Link's Down South cookbook features tuna steaks poached until rare in a bright, buttery sauce that's infused with tangy lime and kumquats, spicy jalapeños and fresh mint. Doubled or tripled, it would make an excellent dinner-party dish.
6-ounce tuna steaks, cut 1 1/4 inches thick
extra virgin olive oil
fresh lime juice
small jalapeño—stemmed, seeded and minced
kumquats, thinly sliced
mint leaves, torn
Season the tuna steaks with salt. In a medium saucepan, melt the butter in the olive oil and lime juice. Stir in the minced jalapeño and sliced kumquats. Add the tuna steaks and cook them over moderate heat, turning once, until they're rare, about 4 minutes.
Transfer the tuna steaks to a carving board and slice them 1/3 inch thick, then arrange them on plates. Stir the torn mint into the sauce, spoon over the tuna and serve.
