Pupusas de Queso (Cheese-Stuffed Tortillas)

Stir the masa harina and water together in a mixing bowl until smooth; knead well. Cover bowl and let the dough rest 5 to 10 minutes.

Shape the dough into eight 2 inch diameter balls. On a lightly floured surface roll out each ball into 6 inch diameter round. Sprinkle 1/4 cup queso fresco over each round. Place a second tortilla over the cheese and pinch the edges together to seal in the cheese.

Heat ungreased skillet over medium-high heat. Place one tortilla into the skillet at a time and cook until cheese melts and tortillas are lightly browned about 2 minutes on each side.
