I marinate tuna filets in soy, ginger, a little olive oil, and brown sugar. Grill on med/hot grill for 3-4 minutes depending on how thick the fish is. It is best to me if it is rare to med rare.
1/4 cup of water
2 tablespoons of unsalted butter
2 tablespoons of tequila
2 tablespoons of lime juice
1 tablespoon of sugar
1 teaspoon of chicken bouillon granules(I get them from ramen noodles)
1 teaspoon of ground coriander
1 teaspoon of crushed red pepper
1 teaspoon of kosher salt
1/2 teaspoon of black pepper
put in a sauce pan and heat until the butter melts and everything is mixed. let it cool down and pour on the tuna in a baking dish or plastic bag, let it sit for half hour to an hour. throw in on the grill 5-7 minutes per side for medium rare and enjoy.
those both sound good. I'm headed for a dinner tonight and will put some in the oven for tonight with olive oil, soy and various seasonings and try the others for the rest of the fish. Thanks guys.
