Ingredients:

For the chicken:

• 2 pounds chicken wings or chicken pieces of your choice
• 1 cup all-purpose flour
• 1 cup cornstarch
• 1 teaspoon baking powder
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 cup cold water
• Oil for frying

For the yangnyeom sauce (sweet and spicy sauce):

• 1/4 cup gochujang (Korean red pepper paste)
• 2 tablespoons ketchup
• 2 tablespoons soy sauce
• 2 tablespoons rice vinegar
• 3 tablespoons honey or brown sugar
• 2 tablespoons sesame oil
• 3 cloves garlic, minced
• 1 teaspoon grated ginger
• 1 tablespoon sesame seeds
• 2-3 green onions, chopped

1. In a large mixing bowl, whisk together flour, cornstarch, baking powder, salt, and black pepper. Gradually add in the cold water while whisking until you get a thick, smooth batter.
2. Add the chicken wings or chicken pieces into the batter and toss to coat them evenly.
3. Heat the oil in a deep frying pan or a deep fryer to 350°F (180°C).
4. Carefully drop the battered chicken wings or chicken pieces into the hot oil, one by one, and fry in batches for about 10-12 minutes or until they are golden brown and crispy. Make sure to flip them occasionally for even cooking. Remove from the oil and place on a paper towel-lined plate to drain excess oil.
5. In a separate saucepan, combine all the ingredients for the yangnyeom sauce (gochujang, ketchup, soy sauce, rice vinegar, honey or brown sugar, sesame oil, minced garlic, grated ginger, sesame seeds, and chopped green onions). Cook over low heat for a few minutes, stirring constantly, until the sauce thickens slightly.
6. Once the fried chicken is done, toss them in the yangnyeom sauce until they are evenly coated.
7. Serve the Korean fried chicken hot, garnished with additional sesame seeds and chopped green onions, if desired.

Note: You can adjust the amount of gochujang and honey/brown sugar in the sauce to your desired level of spiciness and sweetness.

Enjoy your homemade Korean fried chicken with its delicious crispy texture and sweet and spicy flavors!
