Place flour and butter in a food processor and pulse a couple of times until it resembles breadcrumbs

Add the cheese and pulse again until it's all mixed together

Add 2 tablespoons soda water or ice cold water and pulse until the mixture forms a dough. Add a tablespoon or two more water if required

Place the mixture on a flat surface dusted with flour. Bring the dough together, do not overhandle the dough. Roll out and place in a 22cm tart tin, must overlap slightly as the dough shrinks

Refrigerate the pastry for 30 minutes

After 30 minutes prick the dough with a fork and line it with some parchment paper. Place some pie weights or dry beans or rice on top and bake at 200 degrees celcius for 20 to 25 minutes
