Step-by-step instructions

1. 1

   Heat the oil in a large, deep pan, then fry the onions, ginger, garlic and chilli for 10-15 mins until soft. Add the remaining ingredients and some seasoning, then boil for 30 mins, stirring occasionally, until the mixture has thickened and is sticky.

2. 2

   Cool slightly, then whizz in a blender or food processor until smooth. If the sauce is a bit thick for your liking, stir in a dribble of boiling water. Sieve, then funnel into a bottle or jar while still hot. Cool completely before serving. Will keep for 3 months in the fridge.
