Empanada Dough

Directions

1. 1
   Sift flour with salt into a large bowl and blend in butter with your fingertips or a pastry blender until mixture resembles coarse meal with some (roughly pea-size) butter lumps.
2. 2
   Beat together egg, water, and vinegar in a small bowl with a fork.
3. 3
   Add to flour mixture, stirring with fork until just incorporated.
4. 4
   (Mixture will look shaggy.)
5. 5
   Turn out mixture onto a lightly floured surface and gather together, then knead gently with heel of your hand once or twice, just enough to bring dough together.
6. 6
   Form dough into a flat rectangle and chill, wrapped in plastic wrap, at least 1 hour.
