Chop the chillies, peppers and tomatoes fine using a food processor.
Peel and grate the ginger.
Place the chopped chillies, peppers, tomatoes, ginger, sugar, red wine vinegar and lemon zest in a wide saucepan.
Add water and bring to a boil. Cook at high heat for 10 – 15 minutes, regularly checking to skim the “foam” from the surface of the jam.
Reduce the heat to a simmer and allow the jam to slow cook for the next 45 minutes, until reduced, sticky and jammy. If you run a spoon through the jam, and it leaves a trail – it’s ready.
Leave to cool and transfer to a glass jar, with sealed lid. Refrigerate for up to two weeks.
