Directions :
1. In a large bowl, combine masa harina, flour, baking power and 1/2 teaspoon salt. Slowly add water until a soft dough is formed. Transfer dough to floured surface; knead by hand for 5 minutes until dough is smooth. Cover in plastic and set aside.
2. On a lightly floured surface, roll dough to 1/4 inch thick. Using cookie or biscuit cutter, cut into 2-1/4 inch circles. Re-roll remaining dough, as needed, to get 24 circles.
3. Heat 10-inch cast iron skillet over medium heat until hot; add oil. Fry sopes about 5 minutes or until golden brown and edges are crispy; turning once. Transfer sopes to paper towel-lined plate. Season with salt and pepper, as desired.
4. Meanwhile, in a small sauce pan, combine beef, lime juice, orange juice, cumin, chile power, coriander, garlic powder and remaining 1/4 teaspoon salt. Heat over medium heat until hot, about 5 minutes.
5. Remove from heat; stir in tomatoes and jalapeño peppers. Keep warm.
6. Top each sope with beans then beef mixture. Garnish with cheese and cilantro, as desired.
Enjoy !!
