Simon and Dave served up a delicious citrus meringue pie with chocolate pastry on The Hairy Bikers Comfort Food show.

The duo says: “The chocolate pastry is rich and needs careful handling as it is quite soft, so give it a long chill if possible. Don’t roll it too thin as it needs to be robust enough for the filling and meringue.”

The ingredients for the chocolate pastry are: 175g plain flour, 50g cocoa powder, 50g icing sugar, 150g butter, chilled and diced, 1 free-range egg yolk, pinch salt and chilled water.

For the filling: 3 large oranges, zest and juice, 1 pink grapefruit, zest and juice, 75g cornflour, 500ml freshly boiled water and 4 free-range egg yolks.

For the meringue topping: 5 free-range egg whites, 225g caster sugar, ½ tsp cream of tartar and 100g shelled hazelnuts, toasted and lightly crushed or broken up.
