It may be conjecture but even the thought of it….eeeewww!

My mother’s recipe is lost to me so:
How to make empanada dough for baking | Laylita’s recipes
Another recipe for empanada dough from a Chowhoud reader
Ingredients
~~~~~~~~~
2 1/4 cups unbleached all-purpose flour
1 1/2 teaspoons salt
1 stick (1/2 cup) cold unsalted butter, cut into 1/2-inch cubes
1 large egg
1/3 cup ice water
1 tablespoon distilled white vinegar
Preparation
~~~~~~~~~~
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.
Beat together egg, water, and vinegar in a small bowl with a fork. Add to flour mixture, stirring with fork until just incorporated. (Mixture will look shaggy.)
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. Form dough into a flat rectangle and chill, wrapped in plastic wrap, at least 1 hour.
Cooks’ note:
Dough can be chilled up to 6 hours.
