Heat the oil in a wok or large frying pan until very hot.
Whilst the oil is heating, place the cornflour, salt, pepper, garlic granules and paprika into a Tupperware container and mix together.
Add the chicken to the cornflour tub, place on a lid and shake well to cover. Ensure the chicken is fully covered.
Add covered chicken 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. Set aside when cooked.
Add 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.
Serve with boiled rice and top with sesame seeds and spring onions.
