Debone chicken leg, if not already done. Debone by making a vertical cut to expose the bone and then use a sharp knife to cut around the bone
Maximize the area of the chicken by making a butterfly cut or cuts in the thickest part of the chicken and then open flat like a book butterfly cut is when you cut horizontally (parallel to the outer surface) without cutting through to increase the area of the meat
Marinate the chicken with 1 egg, ½ tsp sugar, ¼ tsp 5 spice powder, ⅛ tsp ground black pepper, 1 tsp light soy sauce, 3 slices ginger, and 3 cloves of chopped garlic. Let sit for at least 30 minutes. 2 hours of marinating would be optimal If you like ginger, you can mince or even grate the ginger so that it will adhere to the chicken
Make seasoning powder by combining ½ tsp chicken broth powder, ½ tsp salt, ½ tsp sugar, ¼ tsp white pepper powder, ¼ tsp 5 spice powder and ¼ tsp garlic powder. Pour into a spice shaker for easy dispensing. I used a small strainer which worked too
Pour approx. 100g of sweet potato starch onto a plate
After marinating, mix the chicken around the marinade one last time to absorb as much of the marinade as possible. Place a piece of chicken onto the sweet potato starch and cover completely on both sides. Use a spoon to help spread it evenly. Place on a plate. Let it sit for 5-10 minutes before frying so that the starch can better adhere to the chicken. Repeat for all the chicken pieces. Add more sweet potato starch if necessary
Pour 500ml of oil into a pan. Oil should be able to cover at least half of the thickness of the chicken
Heat oil to 160˚C or 325˚F, add chicken one piece at a time while making sure that the chicken doesn’t touch one another. Cook each side for approx. 3 minutes. Remove from oil and let rest on a cooling rack. Repeat and continue to fry the other pieces of chicken, if any are left
Turn heat up to 200˚C or 400˚F.
Fry the chicken a second time for around 30 seconds each side or until you get a golden brown colour. Remove from oil and let rest on cooling rack
Sprinkle seasoning powder on both sides of the chicken
Cut into strips or leave as is
Serve on its own, with rice, noodles or bread.
