Empanadas de Cebolla, Chipotle y EpazoteThese turnovers have a vegetarian filling sealed inside a rich flaky pastry. Make picnic-size 4-inch turnovers, or cut small pastry circles for cocktail appetizers.
In a medium skillet, heat the oil over medium heat and cook the onion, stirring frequently until very soft and all juices have cooked away, about 10 minutes.
Stir in the salt, chipotles, and epazote.
Cook for 1 minute.
Transfer to a plate and cool completely.
Preheat the oven to 400°.
Place half of the reserved dough on a floured board and roll out thin.
Cut into 4-inch circles.
Gather the scraps and re-roll.
Put 1 tablespoon of the filling on each circle and fold in half.
Moisten the edges with water and crimp with a fork or fingers to seal.
Place on an ungreased baking sheet.
Brush the tops with beaten egg white and bake until golden brown, about 15 minutes.
Cool on a rack.
Repeat rolling, filling, and baking with the remaining half of the dough.
