Execution
Follow the master commands
First, make the pastry. Tip the ingredients into a food processor with 1 /4 tsp salt. Blend until the mixture resembles breadcrumbs. Drizzle 2-3 tsp cold water into the funnel while the blade is running – the mixture should start to clump together. Tip onto a work surface and bring together, kneading briefly into a ball. Pat into a disc, wrap in cling film, and chill for at least 20 mins. Heat oven to 200C/180C fan/gas 6.
Remove the pastry from the fridge and leave at room temperature for 5 mins to soften. Flour the work surface, then unwrap the pastry and roll to a circle the thickness of a £1 coin. Use the pastry to line a deep, 23cm round fluted tin – mine was about 3cm deep. Press the pastry into the corners and up the sides, making sure there are no gaps. Leave 1cm pastry overhanging (save some of the pastry scraps for later). Line with baking parchment (scrunch it up first to make it more pliable) and fill with baking beans. Blind-bake for 15-20 mins until the sides are set, then remove the parchment and beans and return to the oven for 5 mins until golden brown. Trim the pastry so it’s flush with the top of the tin – a small serrated knife is best for this. If there are any cracks, patch them up with the pastry scraps.
