Instructions
Put the flour, sugar and salt in the bowl of a food processor and pulse briefly to combine. Add the cubed butter and shortening and pulse again until they are roughly blended in and mixture resembles breadcrumbs. Combine vinegar and water and add to the dough in a slow drizzle while pulsing. Stop when the dough forms clumps. You may not need to add all the water or you may need to add a touch more if dough is too crumbly. Gather the dough into a ball, divide into two sections, flatten to form two disks, cover with cling film and chill for an hour (or up to a day).
Dust your worktop with flour and roll out half the dough to form a 33cm (13inch) round. Fit the dough over a 23cm (9inch) pie tin and trim any large overhang. Crimp the edges and then chill for 30 minutes.
Put all the ingredients for the crumble topping into a bowl and then use your fingertips to rub the butter into the other ingredients. Chill until needed.
In a bowl, combine the rhubarb, raspberries, sugar and cornflour. Sprinkle a little of the crumble on the prepared pie tin and then add the filling. Top with the remaining crumble topping and sprinkle with the Demerara sugar.
Preheat the oven to 190C (375F) and place the pie on a heavy tray lined with baking parchment (to catch any drips) and bake for 1 –1 1/2 hours until the filling is bubbling and crust is golden. You might need to cover the pie after half an hour if the topping is colouring too quickly. Let the pie cool completely before serving. The pie will be easier to slice the following day.
Notes
You can use the extra dough to make a second pie or use it in pot pies. Recipe adapted from Martha Stewart Pies & Tarts.
