Ingredients
- 2 tbsp olive oil
- 2 red onions, roughly chopped
- 4 clove/s garlic, chopped
- 1 tbsp ground coriander
- 1 tbsp ground cumin
- 1 tbsp ras el hanout
- 4 tbsp red wine vinegar
- 4 x 400g cans finely chopped tomatoes
- 170g dark brown soft sugar
- 4 tbsp rose harissa paste
- 1 tbsp fine sea salt
Method
Heat the oil in a large, heavy-based pan. Add the onions and a large pinch of salt, then cook, stirring, for 15 minutes over a low-medium heat until softened and caramelised. Add the garlic, cook for 2 minutes more, then add the coriander, cumin and ras el hanout. Cook, stirring, for 2 minutes more.
Add 3 tbsp of the vinegar and all the other ingredients. Cook over a low heat, uncovered, for 1 hour, stirring regularly, until thickened and glossy. Leave to cool completely. Meanwhile, sterilise 4 x 400g bottles (find instructions at waitrose.com/howtosterilisejars).
Add the remaining vinegar to the ketchup, then whizz until smooth in a blender. Spoon or funnel into the bottles. The ketchup will keep for up to 2 weeks unopened in the fridge; use within 3 days once opened.
