For the chillies in lemon juice,combine all the ingredients in a small bowl. Roughly chop the chicken to a coarse mince. Combine with the soy sauce,sesame oil and cornstarch and set aside.
Heat the oil in a wok and fry the basil leaves in batches until crisp. Be careful in case the leaves spit (see tip). Remove the leaves from the wok and set aside. Remove about half the oil,set it aside for another use,and return the wok to the heat.
Add the garlic and spring onions and fry until fragrant,about 2 minutes. Add the marinated chicken and fry until browned,about 4 minutes. Add the dark soy sauce and sugar and fry for a further 1-2 minutes until the chicken is coated and any liquid in the wok has thickened. Transfer to a serving plate and scatter with the basil leaves to serve.
Adam's tip Be careful when frying fresh herbs in oil. Any moisture on the leaves will spit,so watch out for flying – not frying – oil.
