Preheat the oven to 375°F (190°C). Lightly grease 2 mini muffin tins.
In a bowl, mix together the flour, baking powder, salt, cumin, and water. Mix it with your hands until a soft dough forms. I should be soft and pliable, not dry. If dry, add a tablespoon of water at a time, until you have a slightly sticky dough.
Leave it in the bowl, cover it, and let rest for 20 minutes.
Form 24 even balls with the dough. Keep the balls covered with a damp towel as you work, so they don’t dry out.
Press each ball into the muffin tins, creating a cup.
Bake for 20 minutes, until firm. Let rest for 5-10 minutes.
Stuff the pockets with carnitas, onions, cilantro, and sriracha mayo.
