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 to make cups. Bake for 20 minutes. Let cool slightly.
Stuff the pockets with carnitas, onion, cilantro and sriracha mayo.
