Heat the oil in a wok or large frying pan until very hot.
5 tablespoons vegetable oil
Place the egg in one shallow bowl and the corn flour in another shallow bowl. Add the flour, salt, pepper, garlic salt and paprika to another shallow bowl and mix together.
2 eggs, 3 tablespoons corn flour, 10 tablespoons plain all-purpose flour, ½ teaspoon salt, ½ teaspoon pepper, ½ teaspoon garlic salt, 2 teaspoons paprika
Dredge the chicken in the corn flour, then dip in the egg (make sure all of the chicken is covered in egg wash), and finally dredge it in the seasoned flour. Add to the wok and cook on a high heat for 6-7 minutes, turning two or three times during cooking, until well browned. You may need to cook in two batches (I find I can do it in one batch so long as it's no more than 3 chicken breasts). Remove from the pan and place in a bowl lined with kitchen towels.
3 chicken breast fillets
Mix all of the sauce ingredients to the hot wok, stir and bubble on a high heat until the sauce reduces by about a third (should take 2-3 minutes). Add the chicken back in and toss in the sauce to coat. Cook for 1-2 minutes.
1 tablespoon sesame oil, 2 garlic cloves, 1 tablespoon Chinese rice vinegar, 2 tablespoons honey, 2 tablespoons sweet chili sauce, 3 tablespoons ketchup, 2 tablespoons brown sugar, 4 tablespoons soy sauce
Turn off the heat and divide between four bowls. Serve with boiled rice and top with sesame seeds and spring onions.
