Dissolve the sugar and salt in 1/3 cup water and chill until cold.
Pulse the flour and butter in a stand mixer until the mixture looks like coarse meal with some pea-size pieces. Add the water all at once and mix until the dough almost forms a ball. Divide the dough in half and flatten into two disks.
Wrap each disk tightly in plastic wrap and chill until firm, at least 30 minutes or up to 3 days. You can freeze the dough for up to 3 months. Thaw overnight in the refrigerator before rolling.
