Cut chicken into bite‑size pieces.
Season with salt, pepper, minced garlic, and vinegar. Massage gently.
Microwave for 30–60 seconds to speed up seasoning. Do not cook the surface.
Mix frying powder and water in a 1:1 ratio to make the batter.
Dip chicken pieces into the batter.
Place dry frying powder in a container. Add chicken pieces and shake until fully coated.
Heat oil. Test by dropping a bit of batter into the oil. If it floats in 3 seconds, it’s ready.
Fry chicken for about 7 minutes, stirring so pieces don’t stick.
For spicy chicken, combine gochujang, ketchup, soy sauce, chili flakes, sugar, garlic, and starch syrup. Boil until slightly thick.
Toss fried chicken in the sauce or serve plain for the classic crispy version.
Optional: If using bone‑in chicken, fry once, remove, then double‑fry on medium‑high heat.
