Let’s start with crust pie

Flour with salt and butter in a bowl

Mix the flour with salt and chilled butter. Using a hand begin to knead.

Slowly add iced water (very cold water) and work with your hand until the dough comes together.

Divide the dough into two parts, wrap it with a cling film and refrigerate at least for half an hour. 

Let’s do Filling

Boil potatoes in fresh water with a pinch of salt.

Cook until tender then drain, mash them and set aside for later. 

Peel, quarter and slice onions. Grate cheddar cheese (or use ready-grated).

Cheese and Onion filling ready to make a pie

Season with salt and pepper, add grated cheese and use a spoon to mix it all. 

Preheat the oven to 200C and prepare an ovenproof dish.

I used an oval dish with a length of 28cm and a width of 19cm. 

Take the pastry out of the fridge.

On a floured surface, roll out both parts of the dough to a thickness of around 6 mm.

Line the bottom of the dish with the first part of the pie crust.

To make it easier to spread the pastry on the dish after rolling out, roll it onto the rolling pin and roll it out onto the dish with the rolling pin.

Put into the filling and using a spoon even it out.

Covering the dish with a second layer of pie crust

Cover with the second layer of crust pie, pressing it down so that it sticks well.

Trim the edges with scissors and close both layers with your fingers to create a pattern.

Let’s prepare eggwash

In a small bowl combine egg yolk and milk.

Top of the pie egg washed from the top just before baking

Brush the pastry with this mixture.

Use a knife to make 4 holes in the centre of the dough to let steam run out.
