Heat oven to 180C/fan 160C/gas 4. Heat 1 tbsp oil in a large casserole dish with a lid. Add the chicken and cook for about 7-10 mins until golden
all over, then remove from the pan. Fry the onion with the bay leaves and the spices in the remaining oil for about 5 mins, until soft and golden. Take off the heat and return the chicken to the pan.
Mix the yogurt, coriander, curry paste and sultanas together, pour over
the chicken and give it a stir. Cover with the lid and cook in the oven for
30 mins, or until the meat falls easily off the bone. Great served with
