Notes
To make shortcrust pastry in advance: Make the pastry and wrap it well in cling film. Store for 2-3 days in the fridge. When ready to use, let it sit on the benchtop to soften for about 30 minutes or so.To freeze shortcrust pastry: Wrap the pastry well into a ball and cover it tightly with cling film. It will last for up to 3 months in the freezer.To blind-bake shortcrust pastry: Roll the pastry out and arrange it in a tin. Place some scrunched-up baking paper covering the pastry, then add baking beans. Preheat the oven to 180C/160C fan-forced and bake for 20 minutes. Remove the tart from the oven, take the baking paper and baking beans off, then return to the oven for 5 minutes. Then, proceed with your recipe.
