Ingredients

250 gr Smoked Marlin or Tuna
600ml milk
6 to 8 large potatoes
pinch salt
50g butter
1 1/2 tablespoons plain flour
2 tablespoons chopped parsley
100g grated cheese

Method

Flake the smoked Marlin or Tuna
Peel and chop the potatoes, then boil with a pinch of salt until soft

Once potatoes are done, drain, then add 30g of the butter and a splash of the reserved milk and mash.

In another saucepan melt the remaining 20g of butter on a medium heat and slowly add the flour stirring constantly until you get a smooth paste.
Add the remaining milk a little bit at a time, stirring constantly, until you get a sauce-like consistency.

Add the parsley and stir well. Cook for 5 minutes, constantly stirring.

Add the sauce to the flaked fish and mix well. Top with the mashed potato and spread evenly. Sprinkle the grated cheese evenly over the potato topping.

Place back in the oven for 30-40 minutes, or until the cheese is bubbling and slightly golden brown.

Take out of the oven and leave to cool for 5 to 10 minutes.
