Place the flour, salt, and sugar into a bowl. Add the butter and using a pastry blender or a fork and knife, cut the butter into the flour until you the butter is incorporated and is the size of small peas. (You can also use a food processor for this step). Pour in the ice water a few tablespoons at a time while mixing until the dough comes together into a loose ball. Dump onto a floured board and knead into a ball (don’t overknead the dough). Wrap in plastic wrap and refrigerate for at least 30 minutes.
