Seared Tuna With Citrus Sauce Recipes

Steps:

• Stir together 1/2 cup olive oil, 1 tablespoon parsley, and red pepper flakes. Toss tuna with marinade, and set aside to marinate for 30 minutes.
• Pour vinegar, orange juice, lemon juice, lime juice, and soy sauce into the bowl of a blender. Add shallot, 1 tablespoon parsley, thyme, dill, honey, Dijon mustard, jalapeno, and ginger. Blend on high until smooth, then add 3/4 cups olive oil in a slow, steady stream with the blender running. Season to taste with salt and pepper, and set aside.
• Bring a large pot of salted water to a boil over high heat. Fill another large container with half ice, half cold water, and set aside. Add the haricots verts to the boiling water, and cook until just tender, 35 to 40 seconds. Remove from the water, and immediately plunge into the ice water to cool. Next, blanch the carrots until just tender, about 1 1/2 minutes; chill in ice water until cold.
• When the vegetables are cold, remove from the ice water and pat dry. Place into a large bowl, and toss with the halved tomatoes, olives, onion, and chervil; set aside.
• Heat a heavy-bottomed skillet over high heat until very hot. Remove tuna steaks from marinade, and wipe off excess marinade. Season the tuna to taste with salt and pepper, then sear in hot skillet to desired doneness, about 1 minute per side for rare.
• To assemble, toss the vegetable salad with enough dressing to lightly coat. Divide the salad among 4 plates, and place a seared tuna steak on top of each. Drizzle with additional dressing to serve.

Steps:

• Rub tuna steaks with peppercorns and set aside while you make the salsa.
• To make the salsa, section oranges, removing all peels and pith. Chop orange sections into 1/2-inch pieces. Combine orange with onion, cilantro, olive oil and lime juice. Toss together, season with salt and cayenne and set aside. Rub a cast iron grill pan with oil and heat. Grill tuna, turning once, until desired degree of rareness is reached, from 2 to 5 minutes per side, depending on thickness. Serve topped with citrus salsa.

Steps:

• Gremolata:
• Before cooking the tuna, combine the parsley, lemon zest and orange zest in a small bowl. Stir in the finely chopped garlic and reserve.
• Cut the tuna into bricks about 3 inches long and 2 inches wide, 3 pieces per portion. Season the tuna with rosemary, salt and pepper, to taste. Drizzle with extra-virgin olive oil and let stand for 10 to 15 minutes. When ready to cook, heat a healthy drizzle of extra-virgin olive oil in a skillet over medium-high heat. When the oil is hot add the tuna and cook for 2 minutes on each side for rare, 3 to 4 minutes on each side for opaque fish. Douse the pan with the lemon juice. Arrange the fish on a platter, scatter the gremolata over the top and serve.

Steps:

• Make sauce:
• In a large saucepan combine citrus juices, tamari or soy sauce, vinegar, oil, and gingerroot and simmer 15 minutes. Pour sauce through a fine sieve into a bowl. (Sauce may be made 1 day ahead and chilled, covered. Reheat sauce before preceeding.)
• Preheat oven to 400°F..
• In a large non-stick skillet, heat oil over moderately high heat until hot but not smoking. Coat 2 tuna steaks with sesame seeds and sear 1 minute on each side, transferring to a baking sheet. Coat and sear remaining 4 tuna steaks in batches in same manner. Cook tuna in middle of oven 3 minutes for medium-rare.
• Cut each tuna steak into 4 slices and arrange slices, cut side up, on 6 plates. Pour about 1/4 cup sauce around tuna on each plate.
