Place the tomato ketchup, tamarind paste and water in a large mixing
bowl and blend together with a fork.
Add the chilli powder, salt, sugar, ginger, garlic, coconut, sesame and poppy
seeds, ground cumin and ground coriander to the mixture.
Add the
cubed chicken cube and stir until well coated with the spice mixture. Set to
one side.
Heat the oil in a deep frying pan such as a wok or kahari. Add
the curry leaves, onion seeds, dried red chillies and fenugreek seeds and fry for
about a minute.
Lower the heat to medium and add the chicken and sauce.
Stir the chicken around well with a slotted spoon.
Simmer gently for
about 12-15 minutes, or until the chicken is thoroughly cooked.
