This is the ideal pie crust for Cheddar-Crusted Apple Pie.
In a food processor, briefly pulse flour, sugar, and salt. Add butter and cheddar; pulse until mixture resembles coarse meal with a few pea-size pieces of butter remaining. Sprinkle with 1/4 cup ice water. Pulse until dough is crumbly but holds together when squeezed (if necessary, add up to 1/4 cup more water, 1 tablespoon at a time). Don't overmix.
Turn out dough onto a floured surface and divide dough (one portion should be slightly larger than the other). Shape each portion into a disk. Wrap each disk separately in plastic and refrigerate until firm, about 1 hour or up to 1 day. (Dough can be frozen up to 1 month; thaw overnight in refrigerator before using.)
