Ingredients

3 tbsp. soy sauce

1 tsp. sugar

tsp. dried red-pepper flakes

1/2 c. canned low-sodium chicken broth or homemade stock

4 tuna steaks

1/2 tsp. salt

1/2 tsp. fresh-ground black pepper

2 tbsp. Cooking oil

1 tsp. Asian sesame oil

1 scallion including green top

3 cloves garlic

Preparation

Step 1In 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.Step 2Reduce 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.Step 3Fish Alternatives: Salmon fillets or steaks will also go well with this highly seasoned sauce.Step 4Test-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.Step 5Wine Recommendation: An aromatic white wine with just a touch of residual sweetness will buffer the spiciness of this dish and balance the saltiness from the soy sauce. Try a luscious sauvignon blanc from New Zealand or California.
