Crispy Sesame Chicken with a sticky asian sauce

This a recipe Helen did - modified because it was a but too sweet and not spicy hot enough

Ingredients

chicken: 2 chicken breast fillets - chopped into bite-size chunks; 5 tbsp Vegetable oil; 2 eggs - lightly beaten; 3 tbsp cornflour (cornstarch); 10 tbsp plain (all-purpose) flour; ½ tsp salt; ½ tsp pepper; ½ tsp garlic salt, or just salt; 2 tsp paprika

sauce: 1 tbsp sesame oil - optional - you can leave out and just sprinkle with plenty of sesame seeds at the end if you prefer; 2 cloves garlic - peeled and minced; 1 tbsp Chinese rice vinegar - white wine vinegar will work too; 1 tbsp honey; 2 tbsp sweet chilli sauce - use more or less depending on the brand and how spicy you like it; 3 tbsp ketchup; 1 tbsp brown sugar; 4 tbsp soy sauce; 1 tsp piri-piri or chilli powder

Heat the oil in a wok or large frying pan until very hot.
Whilst the oil is heating, place the egg in one shallow bowl and the cornflour in another shallow bowl. Add the flour, salt, pepper, garlic salt and paprika to another shallow bowl and mix together.
Dredge the chicken in the cornflour, 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.
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.
Turn off the heat and divide between four bowls. Serve with boiled rice and top with sesame seeds and spring onions.
