Korean Steak & Mushroom Tacos with Kimchi for Two
Mirin is a low-alcohol rice wine essential to Japanese cooking. Look for it in the Asian section of the supermarket or at Asian markets. An equal portion of dry sherry or white wine with a pinch of sugar may be substituted.
Korean chile paste (also called hot pepper paste, gochujang or kochujang) is a fermented spicy condiment made from red chiles, soybeans and salt. Find it in Korean or Asian markets or online from koamart.com. Annie Chun's, a widely distributed national brand of Asian foods, recently launched its own bottled gochujang sauce that is becoming increasingly available in large supermarkets. It keeps indefinitely in the refrigerator. To make a substitute, combine 2 tablespoons each white miso and Asian-style chile sauce, such as sriracha, and 2 teaspoons molasses.
Depending on your region, skirt steak may not be something your supermarket regularly carries--call ahead to make sure it's available or ask your butcher to order it for you. It's usually sold in about 1-pound cuts up to 18 inches long and 5 inches wide, but just 1/4 inch thick. Before cooking, cut the steak with the grain into several portions to make the long piece more manageable on the grill or in a skillet. Once cooked, be sure to slice it across the grain for maximum tenderness. Hanger steak, flat-iron and flank steak can all be used as substitutes for skirt steak in most recipes.
Look for jars of kimchi near other refrigerated Asian ingredients or near sauerkraut or refrigerated pickles in well-stocked supermarkets or natural-foods stores.
To warm tortillas, wrap in barely damp paper towels and microwave on High for 30 to 45 seconds or wrap in foil and bake at 300°F until steaming, 5 to 10 minutes.
