Noodle Preparation (Skip if Using Store-Bought Noodles)
Mix the flour, salt, and water in a bowl “using” a spatula, then form a ball with your hands.
120 g of all-purpose flour, 60 ml water, 0.25 teaspoon salt
Gradually add more water until a dough forms, being careful not to overdo it.
Once the dough is formed, transfer it to a floured work surface and knead about ten times until smooth.
Cover the dough with plastic wrap or place it in a plastic bag and let it rest for at least 30 minutes, or overnight in the refrigerator.
Take out the dough, knead it for 2 minutes, then roll it out thinly on a floured surface into a square of about 10 x 10 inches or a rectangle of 8 x 11 inches.
Dust the surface with flour, fold the dough in layers 4 to 5 times, then gently cut with a knife.
Immediately separate the cut strips to prevent sticking, dust them with flour, and leave them uncovered until cooking.
Beef Topping
Season the ground beef with soy sauce, mirin, and garlic.
85 g of ground beef, 1.5 teaspoons light soy sauce, 1.5 teaspoons of mirin, 0.5 teaspoon garlic
Heat a non-stick pan over medium-high heat and cook the beef until fully cooked, breaking up the pieces.
Set aside to garnish the soup later.
Spicy Sauce (Dadaegi)
In a bowl, mix the green onions (reserve half for garnish), chopped chilies, and sesame oil.
1 tablespoon of green onion, 2 teaspoons of green chili, 0.5 teaspoon sesame oil
Then add soy sauce, vinegar, chili powder, sugar, garlic, and pepper, and set aside.
