Recipes Grilled Tuna with Mint Sauce Be the first to rate & review! Fresh mint blends with garlic, vinegar and sugar for a room-temperature sweet-and-sour sauce that's traditional in England with roasted lamb—and is also perfect for a full-flavored fish like tuna. Serve the rather forceful sauce separately so that each person can decide how much or little to use.Plus: More Grilling Recipes and Tips By Food & Wine Updated on December 2, 2015 Print Rate It Share Share Tweet Pin Email Photo: © Melanie Acevedo Yield: 4 Ingredients 1/2 cup chopped fresh mint 3 tablespoons water 2 tablespoons sugar 1/2 cup white-wine vinegar 2 cloves garlic, minced 3/4 teaspoon salt 4 tuna steaks, about 1 inch thick (about 2 pounds in all) 1 tablespoon olive oil 1/4 teaspoon fresh-ground black pepper Directions Put 1/3 cup of the mint in a medium glass or stainless-steel bowl. In a small stainless-steel saucepan, bring the water to a simmer over moderate heat. Add the sugar and stir until completely dissolved. Stir in the vinegar, garlic, and 1/4 teaspoon of the salt. Pour the mixture over the mint in the bowl. Let sit 15 minutes. Light the grill or heat the broiler. Coat the tuna with the oil. Season with the remaining 1/2 teaspoon salt and the pepper. Cook the tuna for 4 minutes. Turn and cook until done to your taste, 3 to 4 minutes longer for medium rare. Strain the mint sauce through a sieve into a sauceboat or serving bowl. Stir in the remaining mint. Pass the sauce with the fish. Notes Fish Alternatives Mackerel and salmon are both full-flavored enough to take on this sauce. Suggested Pairing Look for the lightest, leanest white you can find; anything else will have a tough time with the mint. Try a Verdicchio-based wine from Italy or a Vinho Verde from Portugal.
