Do I really have to double fry?
For true Korean-fried-chicken crunch, yes. The first fry cooks the chicken and sets the coating. The second fry makes it audibly crispy. If you only fry once, it will still be good, but it will not be that.
Why cornstarch and flour together?
Cornstarch brings the crisp, brittle texture. A little flour adds structure and helps prevent a coating that is too fragile. Think of it as crunch with a seatbelt.
Why is there egg in a mostly dry coating?
It is a light binder. A thin egg-and-water film makes the starch mixture cling so you get an even crust that stays put in the oil.
Can I use boneless chicken?
Yes. Use boneless skinless thighs cut into 1.5-inch pieces. Fry about 3 to 4 minutes for the first fry, then 2 to 3 minutes for the second fry, depending on size and how well your oil temperature rebounds. Start checking early and use a thermometer. Aim for 165°F (74°C) in the thickest piece.
What oil is best for frying?
Use a neutral, high-heat oil like canola, peanut, or vegetable oil. Avoid extra-virgin olive oil here. If you use peanut oil, keep allergies in mind.
How do I keep the coating from falling off?
- Pat the chicken very dry.
- Let the coated chicken rest 10 minutes before frying so the starch hydrates and grips.
- Do not overcrowd the pot. Bubbling oil needs elbow room.
- Let the oil return to the target temperature between batches.
Is gochujang very spicy?
It is usually more sweet and savory than fiery, but brands vary. Start with the amount listed, then add more for heat. You are the boss of your tongue.
Any quick safety tips?
- Fill your pot no more than halfway with oil to prevent boil-overs.
- Lower chicken in gently with tongs or a spider. Never drop it in.
- Keep a lid nearby to smother a flare-up. Do not use water on an oil fire.
- Make sure chicken is patted dry. Water and hot oil are not friends.
Any allergy or gluten notes?
- Gluten: Use tamari (or gluten-free soy sauce) and a gluten-free all-purpose flour blend.
- Peanut: Choose canola or vegetable oil instead of peanut oil if needed.
