Pupusas are those flat Salvadoran cornmeal patties filled with various ingredients (most often meat or cheese). After experimenting—mostly unsuccessfully—to come up with the proper techniques, we invited our Salvadoran friend, Marlene Gomez, to spend an afternoon in our kitchen, teaching us the subtleties of pupusa-making. Our mistake had been to stuff the pupusas as if they were pockets. But the dough needs to be carefully worked around the filling in one piece. Using a bit of rendered pork fat to keep the dough supple, Marlene turned out one beautiful pupusa after another. Soon, we were having a pupusa party.
