Pastry Case

Rub the butter into the flour with the lemon zest and a pinch of salt until it resembles breadcrumbs. Add the sugar, egg and milk and bring together to form a dough. This can be made 2 days in advance.

On a lightly floured surface, roll the pastry out and use it to line a 20cm tart tin, leave 2cm of pastry hanging over the edge. Chill for 30 mins.

Heat oven to 180C. Line the case with baking beans, bake blind for 20 mins, then remove the beans and continue to cook for a further 20 mins until the base is biscuity. Remove from oven and reduce the temperature to 140C.
