Wash chicken and pat dry with
absorbent kitchen paper.
Make 2-3 cuts in meaty parts and
place in a shallow non-metallic dish.
Put tomatoes, tomato purée, chili
sauce, sugar, garam masala, soy sauce, ginger, garlic and lime and
lemon juice in blender or food processor fitted with a metal blade
and process until smooth.
Pour over chicken, cover and leave
in a cool place for 2-3 hours to allow chicken to absorb flavors.
Preheat oven to 190oC
(375oF), Gas 5.
Put chicken and sauce in a roasting
tin and cook, uncovered for 45-50 minutes, basting with sauce 2-3
times, until tender and cooked.
