Ingredients
Method
- Roughly chop the chillies, the garlic and ginger.
- Put them in a food processor and whizz until finely chopped.
- Roughly chop the tomatoes, add to the food processor and blitz until you have a textured mixture. Transfer to a large, heavy-based saucepan and heat over a medium heat.
- Add the sugar, Thai fish sauce and the two types of vinegar. Bring to the boil, stirring, then reduce the heat and simmer for 45-60 minutes until you get a thick, sticky jam. Do stir every 5-10 minutes or so to prevent the jam catching on the bottom of the pan.
- Let the jam cool a bit, then spoon into two sterilized jars.
- Seal, then let it cool completely. Keep in cool, dark place. Once opened, keep the jar in the fridge.
