For the pastry, rub the flour and butter together between your fingertips until the mixture resembles fine breadcrumbs. Bring together with a little water and a small amount of the beaten egg.
Cover in cling film and leave to rest in the fridge for at least half an hour.
Once the pastry is chilled and rested, sprinkle some flour on a worktop and rolling pin. Roll out until fairly thin. Place into a round pie dish and cut away edges. Prick base with a fork.
Preheat the oven to 180oC.
To make the filling, heat the golden syrup gently until it is a thin liquid, but do not let it boil. Finely grate about half the lemon zest, then squeeze in all the juice. Add the breadcrumbs and stir until it becomes a thick mixture.
Spoon the mixture into the pastry case and bake in the oven for 35-40 minutes until the filling is set and golden-brown.
Leave to cool in the tin. Serve warm with custard or cream.
