Soy sauce, sesame oil, scallion, garlic, dried chiles—these traditional Korean flavorings, combined with chicken stock, make an intense and delicious sauce for the tuna. Sautéed spinach or broccoli rabe tossed with a touch of soy sauce and a sprinkling of sesame seeds would be a delicious accompaniment. Plus: More Seafood Recipes and Tips
How to Make It
In a small bowl, combine the soy sauce, sugar, red-pepper flakes, and broth. Sprinkle the fish with the salt and black pepper. Heat the cooking oil in a large frying pan over moderately high heat. Add the tuna and cook until brown, about 3 minutes. Turn and cook the fish until done to your taste, 3 to 4 minutes longer for medium rare.
Reduce the heat to moderately low and put the sesame oil in the pan. Stir in the scallion and garlic and cook, stirring, for 1 minute. Add the soy-sauce mixture; simmer until reduced to approximately 1/3 cup, about 2 minutes. Cut the tuna into slices and serve with the sauce.
Notes
Fish Alternatives Salmon fillets or steaks will also go well with this highly seasoned sauce.
Test-Kitchen Tip We like fresh tuna cooked to a succulent medium rare. If you prefer your tuna cooked through, just add a few more minutes to the cooking time. Be careful not to overcook it, though, or it will most assuredly be dry.
