Knead whole wheat flour, yogurt, salt, and water into a soft dough; rest for 30 minutes.
Roll dough portions into round discs.
Apply water evenly on one side of the rolled dough.
Place wet side onto a hot iron skillet so it sticks.
Flip the skillet upside down directly over open flame to cook and char top side.
