2 green onions, chopped
2 cloves garlic, minced
1 fresh green chili pepper, minced
1 lb tender beef steak (we used 1 inch thick piece of top round)
1/4 cup dark soy sauce
1/4 cup rice wine (sake)
2 tablespoons toasted sesame seeds, crushed*
1 tablepsoon lime juice
1 tablespoon toasted sesame oil
1 teaspoon cornstarch, dissolved in 2 teaspoons of water
2 oz dried shiitake mushrooms
10 oz frozen spinach, defrosted and drained
soba noodles, cooked
Place the steak, soy sauce, chili pepper, sake, sesame oil, lime juice, garlic, sesame seeds and green onions in a large ziplock bag and allow to marinate at least 45 minutes or up to overnight. While the steak is marinating soak 2 oz. dried shiitaki mushrooms in 1 cup hot water. Remove steak from marinade, reserving marinade, and sear on a hot pan. For a 1″ thick steak, cook on high heat for 2.5 minutes on each side for rare steak. Remove steak to a pan and cover with foil. Let sit for 5 minutes and then slice thinly. While steak is cooking, squeeze out mushrooms, reserving liquid, and chop them. Add the mushrooms, cornstarch and liquid to a sauce pan with the marinade. Bring sauce to a boil, cook for 5 minutes and then add the cornstarch mixture. To serve: thinly slice the steak and arrange on a bed of soba noodles and spinach**. Drizzle with sauce.
*This is easiest with a mortar and pestle. In lieu of that, you can crush them between two sheets of wax paper with a rolling pin.
