- 1/3 cup mirin or rice wine
- 1/2 cup soy sauce
- 1 tablespoon sugar
- 2 teaspoons minced gingerroot
- 1 teaspoon minced garlic
- Pinch cayenne
- 4 (5 to 6-ounce) halibut fillets
- About 1/4 cup black and white sesame seeds
- 2 tablespoons vegetable oil
- Minced green onions, as garnish
- Cucumber Noodles 
Combine the mirin, soy sauce, sugar, ginger, garlic, and cayenne in a small saucepan and bring to a boil. Lower heat and simmer until reduced a thick glaze, 5 to 6 minutes. Remove from the heat. Set aside 1/4 cup of the teriyaki sauce.
Set the halibut fillets in a baking dish and sprinkle with cayenne and add the remaining teriyaki sauce. Marinate for 15 minutes and up to 1 hour.
Place the sesame seeds in a dish and dip the fillets onto the seeds, pressing lightly to coat each side with about 1 teaspoon of seeds.
Heat the oil in a large skillet over medium-high heat. Add the fillets and cook until browned and just done, 3 to 4 minutes per side. Remove from the pan to 4 serving plates. Garnish with the green onions and remaining glaze. Serve with the Cucumber Noodles.
