Make the crust first, at least 2 hours before you'll want to use it, or you can even make it and freeze it for easy grab and use! To make the crust, add your flour into a food processor. Cut your butter into small cubes and add on top. Add sugar and salt. Pulse a few times to get a sand like consistency, then slowly add in iced water, 1 tbs at a time, pulsing as you add it, until the dough just comes together. Then dump it out onto plastic wrap, and wrap into a disc. Place in the fridge for at least two hours, or freeze.
