Gooseberry and cucumber relish

Soften the red onion with the oil and a large pinch of salt in a frying pan set over a medium heat, stirring often. Once the onion is soft, but not coloured – about 5 minutes – stir in the gooseberries, chilli, sugar and 2 tbsp vinegar, then cook for a few minutes more. Once the gooseberries have burst, stir in the ginger, then cook for 1 minute more.

Remove from the heat and add the remaining 1 tbsp vinegar. Allow to cool, then stir in the cucumber and coriander. Taste and add a little more salt if needed. Serve as a relish for grilled salmon, mackerel or halloumi.
