For the dough: Mix the flour and salt in a large bowl. Dissolve the yeast and sugar in 2 tablespoons warm water in a small bowl. Pour the yeast mixture and 3/4 cup water into the flour mixture. Mix together until a soft dough forms, adding more water a little at a time if the dough is too dry. Cover with a towel or plastic wrap and let sit for 15 minutes.
For the filling: Combine the ground beef, onions, tamarind concentrate, tomato paste, pine nuts, lemon juice, salt, allspice, ketchup, cumin, pepper and cayenne in a large bowl and mix until combined.
Preheat the oven to 375 degrees F. Lightly sprinkle a work surface with flour. Roll out the dough 1/4-inch thick. Cut the dough into rounds using a 4-inch cookie cutter. Place the rounds on baking sheets. Spread 1 tablespoon of the meat filling on each round. Bake until the edges are golden brown, 10 to 15 minutes.
