(country of origin: El Salvador)

2 cups Masa harina
1 cup Warm water
1 cup Filling (see variations)

In a large bowl, mix together the masa harina and water and knead well. Knead in more water, one tablespoonful at a time if needed, to make a moist, yet firm dough. (It should not crack at the edges when you press down on it.) Cover and set aside to rest for 5 to 10 minutes. Roll the dough into a log and cut it into 8 equal portions. Roll each portion into a ball. Press an indentation in each ball with your thumb. Put about 1 tablespoon of desired filling into each indentation and fold the dough over to completely enclose it. Press the ball out with your palms to form a disc, taking care that that the filling doesn’t spill out. Line a tortilla press with plastic and press out each ball to about 5-6 inches wide and about 1/4-inch thick. If you don’t have a tortilla press, place the dough between two pieces of plastic wrap or wax paper and roll it out with a rolling pin. Heat an ungreased skillet over medium-high flame. Cook each pupusa for about 1-2 minutes on each side, until lightly browned and blistered. Remove to a plate and hold warm until all pupusas are done. Serve with curtido and salsa roja. Makes 4-5 pupusas
