For the pita bread, put flour, baking powder, salt and pepper in a bowl. Add the butter (in pieces) and crumble with the flour.
Add enough water to make a thick paste. Knead well, refrigerate for 30 minutes, then roll out to about 1/2 cm thick.
Cut out with a glass (about 6 cm). Heat oil in a pan (bottom covered) and put the flatbreads in.
Bake for about 90 seconds, then press on the flatbreads with a wide knife to make them rise. Then turn over and bake the second side.
Drain the fat on a paper towel.
