Preparation

1. Place all the vegetables in a large pot with a splash of olive oil and the ginger, garlic, chilli, basil stalks, coriander seeds and cloves. Season with the pepper and a pinch of salt.

2. Cook gently over a low heat for 10–15 minutes until softened.

3. Add all the tomatoes and 475ml of cold water.

4. Bring to the boil and simmer gently until the sauce reduces by half.

5. Add the basil and whizz in a food processor or hand blender. Strain through a sieve twice to make it smooth.

6. Put the sauce in a clean pan and add the vinegar and sugar. Place the sauce on the heat and simmer until it reduces and thickens to the consistency of tomato ketchup.

7. Correct the seasoning to taste.

8. Spoon the ketchup into sterilised bottles, seal tightly and place in the fridge until required.
