2. Cut off the core of the onion and chop it into large pieces for a satisfying texture. Cut larger pieces in half.
   🕒 01:15
3. Cut the chicken thighs into bite-sized pieces. If they seem too large, cut them in half.
   🕒 01:45
4. In a bowl with the chicken thighs, add the marinade ingredients: salt 1/4 tsp, grated garlic 1 clove, and Cooking Sake (Rice Wine) 1 tbsp. Mix well by kneading. [Secret Tip!] Sake helps to remove any gamey odor and tenderize the meat.
   🕒 01:54
5. While the surface of the chicken is still moist, add Potato Starch 3-4 tbsp and coat the chicken thoroughly and thickly until no dry starch remains. This helps the sauce to adhere better.

6. Heat Vegetable Oil in a frying pan until hot.
   🕒 03:07
7. Add the onions and bell peppers to the hot pan. Once the oil coats them, stir-fry until they start to char.
   🕒 03:13
8. Stir-fry the onions and bell peppers until they slightly change color and develop some char marks on their skins, bringing out their sweetness.
   🕒 03:31
9. Lightly sprinkle a pinch of salt over the stir-fried vegetables and remove them from the pan temporarily.

10. Add more Vegetable Oil to the same pan where you stir-fried the vegetables, and arrange the seasoned chicken pieces.
    🕒 04:36
11. Fry the chicken until it develops a nice golden brown color.
    🕒 04:54
12. Once one side of the chicken is golden brown and crispy, flip it over and cook the other side similarly.
    🕒 05:18
13. In a separate bowl, combine the sauce ingredients: Ketchup 2 tbsp, Vinegar 2 tbsp, Sugar 2 tbsp, Soy Sauce 1 tbsp, Water 6-7 tbsp, and Potato Starch 1 tsp. Mix well. [Secret Tip!] Mixing the potato starch directly at this stage, without dissolving it in water first, saves time.

    🕒 06:29
15. Pour the prepared sauce into the pan and coat the fried chicken thoroughly.
