Stir in the curry powder, turmeric, raisins, vinegar and star anise, and fry for 1 min more, then pour in the chicken stock, bring to the boil and simmer very gently for 30 mins, stirring so it doesn’t catch on the bottom.STEP 2Lift out the star anise, mix the cornflour with 2 tbsp water and stir into the sauce.

If freezing the sauce, leave to cool, pour into a container and freeze, then defrost and reheat when you’re ready to eat.
