For the tomato sauce:
For the mackerel:
- Put all of ingredients (except the basil) into the slow cooker pot and cook on the highest setting for 4-5 hours. Stir in the basil leaves just before serving the sauce with the mackerel.
- Preheat the grill to setting 5. Once heated, rub the mackerel with a little oil, season and place it onto the flat part of the grill, skin side down. If it is a whole fish turn over once the skin starts to be crisp. Cook until the fish starts to flake apart.
Tom’s Tip: Serve with our delicious Saffron rice for a quick evening meal.
