Recipe
Cooking time: 1 hour
Serves: 5
Ingredients
- 1Kg potatoes
- 750g raw mixed fish – cut into pieces around the same size
- 500ml SuperNutrio Whole Milk (or regular cow's milk)
- 200g frozen peas
- 100g mature cheddar cheese, grated
- 50g butter
- 50g plain flour
- 20g fresh chives, finely chopped
- 20g fresh parsley, finely chopped
- 8 large raw king prawns
- 6 spring onions, roughly chopped
- 4 hard-boiled eggs, cut into quarters
- 1 large leek, roughly chopped
- 2tsp Dijon mustard
- Salt and pepper
Method
- Peel the potatoes and chop them into pieces around the same size, to help them cook more evenly.
- Place the potato into a large pot, cover with water and add 2 tsp of salt.
- Bring the water to a gentle boil and continue boiling until the potatoes are fork soft.
- Once the potatoes are done, drain them into a colander and return them to the warm saucepan to steam dry.
- Use a potato masher to mash the potatoes until all of the lumps are gone.
- Pour in 100ml of SuperNutrio Whole Milk.
- Keep mashing until the milk and potatoes are combined into a smooth and creamy mixture.
- Add the grated cheese and the chopped parsley to the mashed potatoes, and mix until everything is well combined.
- Add salt and pepper and set the potatoes aside until later.
- Pour 400ml of SuperNutrio Whole Milk into a saucepan and let it slowly heat until it’s just below boiling point. Take the pan off the heat and set it aside until needed.
- Put 50g of butter into a large saucepan and, on a low to medium heat, let the butter melt.
- Tip in the chopped leeks and let them cook on a low to medium heat for around 3-5 minutes, until they become soft and a little translucent.
- With the saucepan still on the heat, add the flour and stir until it comes together.
- Let the flour mixture cook on the low heat for 2 minutes, stirring all the time.
- Remove the pan from the heat and using a whisk to stir, slowly pour the warm milk into the pan.
- Place the saucepan back on the low heat, and keep whisking and stirring until the sauce becomes thick and smooth – around 3-5 minutes.
- Add the finely chopped spring onions, chopped chives, peas and Dijon mustard to the sauce. Use a spoon to mix this all together. Give the sauce a taste and season if needed.
- Add the raw fish to the sauce and gently mix it in.
- Preheat the oven to 200°C/fan 180°C/gas mark 6. Find an ovenproof dish that will hold the pie, and spoon the filling mixture carefully into the dish, making sure to level the filling.
- Place the quartered hard-boiled eggs and the raw king prawns across the top of the filling.
- Spoon the mashed potato on top and use the back of a fork to make a pattern across the top of the potatoes.
- Place the pie dish onto an oven tray and place carefully in the oven.
- Cook for around 1 hour, until the top is golden brown, the pie is bubbling and piping hot in the middle.
