Pre-heat the oven to 200°C (400℉).
Melt the butter and allow to cool for several minutes.
In a food processor or large bowl, mix the flour, eggs, sugar and melted butter until a crumbly dough forms.
Grease a pie dish - mine was 27cm (10½").
Push the dough evenly into the dish (and a little up the sides) using your hands or the back of spoon. The dough is very pliable, so it should be easy to mould it into the dish.
Place in the fridge for around 10 minutes, just to firm up a little.
Bake for around 10-15 minutes, until golden at the edges, then remove and allow to cool for around five minutes.
