2 peppered smoked mackerel fillets, flaked
75-100g cheddar cheese, grated
4 tbsp horseradish sauce
Preheat the oven to 180°c.
Put a pan of water on to boil. Once boiling add the macaroni to the pan. Cook as per pack instructions.
Meanwhile, melt the butter in a pan. Add enough flour to make a roux. Add enough milk to form a sauce and whisk until smooth. Add the cheese until the sauce is thick, shiny and smooth. Mix in the horseradish sauce.
Strain the pasta and put in a dish layering the flaked mackerel with it. Pour over the cheese sauce, top with more grated cheese and bake until the cheese is melted and golden.
