Put the flour(s) and frozen ice-cubes of shortening into a food processor with the blade attachment inserted.
Pulse the blade until the mixture resembles fine breadcrumbs.
Add in the sugar and pulse a few times to mix in well.
Transfer to a bowl and sprinkle the very cold water into the mixture as you stir it with a fork.
It should clump together, and then form into larger pieces. At this point if it’s not starting to do this, you may need to add a up to a maximum of 1 more tablespoon. Too much water though will make the finished pastry tough.
Form into a dough.
Then on a sheet of greaseproof paper, pat/roll into a disk a little smaller than the pie dish – and refrigerate for 30mins. Use a high sided 8inch removable base pie/tart case.
Roll out to bigger than the pie dish by around 40mm – still on the sheet of greaseproof paper. Slide hand under paper and offer it up to the pie dish & flip over or fold over a rolling pin to transfer it. Wholemeal pastry is more difficult to work with as it’s not so flexible.
Press gently into the edges and smooth the pastry level with the top edge and trim pastry so it’s not above the lip, with a table knife.
Cut the same greaseproof sheet to the size of a large dinner plate and cut strips radially around the edge.
Drop paper into pie dish and smooth into edges
then pour some baking beads in so you have a single layer of beads completely covering the base. Bake at 200°C (190°C Fan) for 15 mins until edges are golden brown.
Once pie crust is cooked, remove paper and beads by gathering up and put on a plate or bowl to cool.
