In a liquid measuring cup, whisk together ¼ cup of the water and the yogurt. In a food processor, combine the flour, salt and baking powder. Process 5 seconds.

Add the lard and process until combined, about 10 seconds. With the processor running, add the yogurt mixture.

With the processor still running, add the remaining water 1 tablespoon at a time until the dough forms a smooth ball, about 1 minute.

Divide the dough into 4 pieces. Roll each into a ball, then cover with plastic wrap. Let rest for 15 minutes. Meanwhile, prepare toppings.

Roll each dough ball into a 10-inch round. Poke the surfaces all over with a fork.

Heat a 12-inch cast-iron skillet over medium until a drop of water sizzles immediately, 4 to 6 minutes. One at a time, place a dough round in the skillet and cook until the bottom is charred in spots, 1 to 2 minutes.

Using tongs, flip and cook for 30 seconds. Transfer to a plate and cover loosely with foil.
