In a medium bowl, combine all the sauce ingredients: ketchup, gochujang, honey, brown sugar, soy sauce, water, garlic, red pepper flakes, cornstarch, and sesame oil. Mix well until smooth and set it aside.
In a large, shallow bowl, whisk together the cornstarch, flour, salt, and black pepper.
In another bowl, add the beaten eggs and set this aside.
Cooking
Pour about 2 inches of canola oil into a deep frying pan and heat over medium-high heat.
Dip each chicken piece into the beaten eggs, allowing excess to drip off. Then coat the chicken in the cornstarch mixture.
Once the chicken is coated, arrange the pieces on a plate and let them rest for 10 minutes.
Fry the chicken in batches for 5-7 minutes until golden brown and crispy. Monitor the temperature of the oil.
Remove the chicken and discard the oil. Toss the chicken with the prepared sauce until well coated.
Optionally, serve with a sprinkle of green onions and sesame seeds.
Notes
For an even crunchier texture, try double frying the chicken.
Make extra sauce for dipping or drizzling over rice or veggies.
