METHOD
To make the chermoula paste: mix garlic puree in a dish and stir in the cumin seeds, chilli puree, lemon juice, oil and chopped coriander.
Marinade the fish in half the chermoula paste and leave to stand in the fridge while you cook the rest of the dish.
Meanwhile mix the Cornish New potatoes, tomatoes and olives in a heavy based pan. Add the stock, season, cover and cook gently on the hob for 40 minutes.
Add the fish and cook for a further 15 minutes. Drizzle over the rest of the chermoula paste and serve.
