In a mixing bowl, rub butter (using fingertips) into the flour until it resembles breadcrumbs or sandy texture.Add the egg yolk and egg to bring it into a dough.
Mix, kneading slightly until it comes together. Wrap the dough with cling wrap and freeze for 1 hour.
Preheat the oven to 200℃.
Place the pastry dough between two sheets of baking paper and roll into a circle that is larger than your quiche pan. If it’s too cold/stiff to roll out, leave it for 5 to 15 minutes then continue.
Line the quiche pan and freeze again for 15 minutes, this is for in case the dough is overworked and the butter is no longer cold.
Remove the pastry from the fridge. Prick the pastry in the pan with a fork. Line with baking paper and pour in baking beans.
Bake for 10 minutes, then remove the baking beans and paper and bake again for a further 10 minutes, or until the base is dry and firm.
