Preheat the oven to 200C / 400F / Gas 6.
Mix the soy sauce, sugar, vinegar, sherry, orange juice and peel and
anise in a pan. Bring to the boil. Combine the
cornflour and water in a small bowl and stir until blended. Add to the
boiling soy sauce mixture, stirring well. Boil for another minute,
stirring constantly. Remove the
soy sauce mixture from the heat and stir in the ginger and chilli-garlic
sauce. Arrange the
chicken wings, in one layer, in a large baking dish. Pour over the soy
sauce mixture and stir to coat the wings evenly. Bake in the
centre of the oven for 30-40 minutes until the chicken wings are tender
and browned, basting occasionally. Serve the chicken wings either hot or
warm.
