3 pieces fresh Ahi Tuna, cut in 1 inch pieces
2 teaspoons garlic
1 tablespoon Dijon mustard
2 tablespoons Soy Sauce
1 tablespoon Lemon Juice
Kosher salt and pepper to taste
Mix garlic, Dijon mustard, soy sauce, lemon juice and salt and pepper. Add tuna and marinate for at least ½ hour and up to 2 hours.
Heat a small amount of sesame oil in a pan. When the oil is hot, add the tuna and sear until desired doneness. This is best when the outside is browned and the inside is rare. This is accomplished by using a very hot pan and not moving the tuna while cooking until you are ready to turn it over, which takes about 1 minute of cooking time.
