For tart crust:
Pre-heat oven to 350 F.
Grease your tart pan, this dough caramelizes on the bottom and will stick if not greased.
Mix together the flour, the sugar and salt.
Add the cold butter chunks and use a pastry cutter or fork to work butter into dough until dough starts looks crumby.
Add the cold water one tablespoon at a time and mix until dough can form a ball.
Roll dough out on a piece of parchment paper so it’s thin and the right dimensions for your tart pan.
Place tart pan on top and slide your hand under the parchment paper and flip the pan over with the tart dough on top.
Work dough into the edges of your tart pan then take a knife and trim along the top edge of the tart pan so you have a clean edge.
