In a mixing bowl, combine flour and salt. Cut in butter until mixture resembles coarse crumbs. Stir in water, a tablespoon at a time, until dough forms. Wrap in plastic and refrigerate for 30 minutes.
In a skillet, cook beef, onion, and garlic over medium heat until meat is no longer pink. Drain. Stir in cumin, paprika, olives, and raisins. Set aside.
On a floured surface, roll dough to ⅛-inch thickness. Cut with a 4-inch round cutter. Place a tablespoon of filling on each circle. Fold dough over filling; press edges with a fork to seal. Place on a baking sheet.
Brush with egg wash. Bake for 20 minutes or until golden brown.
