In a large bowl, combine the bulgur, rice flour, all-purpose flour, ground cumin, ground cinnamon, salt, and black pepper.
Slowly add the hot water to the mixture, stirring until the dough starts to come together. Allow it to rest for 10 minutes.
Knead the dough for a few minutes until smooth and pliable. Cover and set aside.
In a large skillet, heat the vegetable oil over medium heat. Add the chopped onion and cook until translucent.
Add the ground beef or lamb to the skillet and cook until browned.
Stir in the pine nuts, currants or raisins, ground cinnamon, ground cumin, ground allspice, salt, and pepper. Cook for another 5 minutes, then remove from heat and allow to cool.
Preheat your oven to 375°F (190°C). Lightly grease a baking sheet or line it with parchment paper.
Take a small piece of dough and flatten it into a thin circle on a piece of plastic wrap or parchment paper.
Place a spoonful of the filling in the center of the dough circle.
Fold the edges of the dough over the filling and seal well, shaping into a small oval or disc.
Place the assembled Kubba onto the prepared baking sheet.
Bake in the preheated oven for 20-25 minutes, or until golden brown and cooked through.
Allow the Kubba to cool slightly before serving.
Enjoy your meal!
