Spiced Herring

• 8 large plain roll mops, rinsed well

Place all the spiced marinade ingredients into a saucepan and bring to the boil. Leave to simmer for 10 minutes, then remove from the heat and leave to cool completely.

Cut the roll mops into 2–3cm (¾–1¼ inch) pieces. Add the roll mops to the cold marinade and top with the red onion slices.
