Ingredients
Method
1.Place flour and salt together in the bowl of a food processor and with the motor running drop in cubes of butter until mixture resembles coarse crumbs. Add egg yolk and water and pulse just until mixture forms a ball. Wrap in clingfilm and refrigerate for 30 minutes.
2.Place sugar, raspberries and rhubarb in a saucepan with 1/3 cup water. Bring to the boil and simmer until rhubarb is just tender. Mix custard powder with 3/4 cup cold water, then add to the fruit mixture and stir over a gentle heat until thickened. Allow to cool.
3.Preheat oven to 180C. Roll out pastry until 2 to 3mm thick. Place pastry on a baking tray and pile the cooled rhubarb mixture into the centre leaving a 12cm border of pastry. Fold the pastry in over the fruit.
4.Brush pastry with egg yolk and sprinkle with sugar. Bake for 20 minutes until pastry is golden and firm.
