Yangnyeom Korean Fried Chicken

In a large bowl, combine the chicken pieces with 1 tbsp soy sauce, 1 tsp minced ginger, 1 tsp minced garlic, mirin, 1/2 tsp salt, and 1/4 tsp black pepper. Mix well to coat all chicken pieces. Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours for best flavor.

In a separate large bowl, whisk together the potato starch, all-purpose flour, and baking powder. Add the cold water and egg, then whisk until a smooth, thick batter forms. Do not overmix; a few lumps are fine. The batter should be similar to pancake batter consistency.

Heat 4-5 cups of vegetable oil in a deep pot or Dutch oven to 170°C (340°F). Dip each marinated chicken piece into the batter, ensuring it is fully coated, and let any excess drip off. Carefully place chicken pieces into the hot oil, frying in batches to avoid overcrowding the pot. Fry for 6-7 minutes until light golden brown and cooked through. Remove with a slotted spoon and place on a wire rack to drain.

While the chicken is frying, prepare the sauce. In a medium saucepan, combine gochujang, gochugaru, 2 tbsp soy sauce, rice vinegar, brown sugar, corn syrup (or honey), 1 tbsp minced garlic, 1/2 tsp minced ginger, sesame oil, and 3 tbsp water. Bring the mixture to a simmer over medium heat, stirring constantly until the sugar is dissolved and the sauce thickens slightly, about 3-5 minutes. Remove from heat.

Increase the oil temperature to 185°C (365°F). Return the first-fried chicken pieces to the hot oil in batches. Fry for another 2-3 minutes, or until the chicken is deeply golden brown and extra crispy. This double-frying step is crucial for achieving the signature crunchy texture of Korean fried chicken. Remove and drain on a wire rack.

Once all chicken is double-fried, transfer the hot chicken to a large mixing bowl. Pour the warm Yangnyeom sauce over the chicken and toss gently but quickly until every piece is evenly coated. Garnish with roasted sesame seeds, chopped peanuts (if using), and sliced green onions. Serve immediately and enjoy your authentic Yangnyeom Korean Fried Chicken!
