Ingredients
- 500g tomatoes
- 4–8 chillies (depending on size and heat preference)
- 4 cloves garlic, peeled and roughly chopped
- 6cm piece of ginger, peeled and roughly chopped
- 30ml fish sauce
- 300g sugar
- 100ml red wine vinegar
Method
- Place half the tomatoes in a blender with the chillies, garlic, ginger, and fish sauce. Blitz until smooth.
- Finely dice the remaining chillies.
- Transfer the purée to a saucepan and add sugar and vinegar. Stir continuously and bring to a boil.
- Once boiling, reduce to a simmer and add the remaining tomatoes.
- Simmer gently for 30–40 minutes, stirring frequently and scraping down the sides to prevent sticking or burning.
- Meanwhile, sterilise jars in the oven at 100°C for 30 minutes. Boil the lids for the final 5 minutes.
- Once the jam has thickened and reached setting point (sticky consistency), pour into the hot sterilised jars and seal.
