3 cups flour (plus a little more for kneading)
1 teaspoon salt
3 tablespoons shortening
¾ cup cold water
1 egg white
2 teaspoons vinegar
Combine flour, salt and shortening in a food processor and pulse until mixture begins to bead and has a sandlike appearance. Combine water, egg, egg white and vinegar into a measuring cup and whisk egg and water together well. Turn food processor on and slowly start to pour water/egg mixture in until gone and dough begins to form. Remove and lightly knead into a ball. Wrap the dough in plastic and refrigerate for at least 1 hour. Makes approximately 12 six-inch empanadas.
Place all contents into a large pot and bring to a boil on high heat. Reduce to a simmer and continue to cook until mixture reduces by 1/4. Allow mixture to cool and puree in blender.
Simmer chicken in salsa roja. Cool, pull meat from bone. Mix in cheese and kale.
Form the dough into 2-inch balls. Roll them out on a floured surface. Spoon in filling and fold dough over to make a half moon. Crimp closed. Deep fry at 350° for 5 minutes or bake at 375° for 15-20 minutes. Serve with crème fraîche and remaining salsa roja.
