Korean Joon Ma Bulgogi Beef Tacos - cooking recipe

Ingredients

2 lbs rib eye steaks
1/4 cup soy sauce
1/4 cup sake
1/4 cup dark brown sugar
1 tablespoon sesame oil
1 teaspoon black pepper
1/2 yellow onion, peeled and cut into chunks
1/2 Asian pear, peeled, cored and cut into chunks
4 garlic cloves
1/2 inch piece ginger, peeled
toasted sesame seeds
canola oil
2 green onions
1 tablespoon rice vinegar
1 tablespoon sugar or 1 tablespoon honey
1 tablespoon minced garlic
1 teaspoon sesame oil
1 teaspoon salt
1 teaspoon toasted sesame seeds
2 -3 teaspoons korean red chili pepper flakes
5 scallions, very thinly sliced on a sharp diagonal (white and green parts)
1/2 cup chopped fresh cilantro
1 avocado, thinly sliced
korean red chili paste
twelve 6-inch white corn tortilla

Preparation

Trim excess fat from steak and slice very thinly across the grain.
Put onion, pear, garlic, ginger and sake into a blender (or food processor). Blend until smooth and creamy. Then add soy sauce, dark brown sugar, sesame oil and black pepper. Pulse until well mixed.
Pour marinade over beef. Gently massage the beef with the marinade for a minute or two. Cover and refrigerate for at least 1 hour or overnight. Remove from refrigerator about 20 minutes before cooking.
Wash the cucumber and slice 1/8 inch thick. Wash the green onion and chop finely.
In a large bowl, mix the rest of the ingredients. Then add the cucumber and green onion and gently mix by hand. Refrigerate for at least 30 minutes.
Very thinly slice the scallions on a sharp diagonal, chop the cilantro and slice the avocado. Put each in a separate serving bowl. Refrigerate until ready to use.
Heat 1 tablespoon of oil in a cast-iron pan over high heat. Add the marinated bulgogi to the pan and cook the beef in batches, each in a single layer. Stir the beef until cooked through and nicely browned and caramelized (about 3 minutes). Be sure not to crowd the beef in the pan or it will end up steaming versus browning. Transfer to a serving plate and sprinkle with sesame seeds.
Heat the tortillas on a hot skillet, turning occasionally, for about 1 minute, or until hot. Transfer to a serving platter and cover to keep warm.
Serve the bulgogi with the tortillas, cucumber salad and garnishes. Let each guest make their own tacos by adding bulgogi to a tortilla and topping it with cucumber, scallions, avocado, cilantro and a drizzle of gochujang.
