2 cups masa harina
1-1/2 cups warm water
Mix masa harina with water, the dough should be as wet as possible without being sticky - like soft playdough. Form the dough into one ball, cover in plastic and let sit for about 30 minutes. Form into balls. Using tortilla press, press them to desired thickness. Slap each one into a hot cast iron skillet (no oil), and flip after 30 seconds. Flip after 30 more seconds, and "tap" and "spin" them so they puff up.
