El Salvador’s national dish: a thick corn flatbread stuffed with cheese and beans and griddled on a comal. The hard part is that masa has no gluten. This site’s wrapping guide answers a splitting seam with pleats, because pleating lengthens the seam and builds in slack — and masa cannot be pleated, since it tears rather than stretches. So a pupusa does the opposite. You close a ball, then flatten it, and the seal is spread across the whole disc until there is no seam left to split.

Steps

Make the curtido first. Pour boiling water over the shredded cabbage, carrot and onion, leave a minute, drain, then toss with the vinegar, oregano and salt and leave at least two hours (fermentation basics).
⏲ 30 min
Work the warm water into the masa harina and salt and knead 3-4 minutes. It should be smooth like modelling clay — if the edge cracks when you press it, it is short of water, so add a tablespoon at a time. Cover and rest it 10 minutes.
⏲ 10 min
Mix the filling. It has to be lump-free and dry. One lump of cheese makes a thin spot in the dough, and that is where it bursts (wrapping and sealing).
⏲ 5 min
Set a bowl of water beside you and wet your hands before every pupusa. Dusting flour does not work on a dough with no gluten — flour only dries it out and cracks it. Water is what stops it sticking.
⏲ 1 min
Roll 60g of dough into a ball and press a bowl shape into it with your thumb. Put in a tablespoon of filling, keeping 1cm clear at the rim, then draw the edges up, pinch it shut and roll it back into a ball.
⏲ 10 min
Flatten it between wet palms, turning as you go, into a disc 10-12cm across and about 1cm thick. Stop at the first sign of filling showing through. This is where the seam gets spread over the whole disc.
⏲ 10 min
Heat a comal or heavy pan to medium and griddle dry, 3-4 minutes a side, until brown mottled patches appear and it puffs slightly. Cheese escaping and catching on the pan is normal, and those bits are the best part.
⏲ 4 min
Eat them with your hands, with curtido and salsa roja.

Tips & Variations

Variations

De queso: cheese only. Frijol con queso: beans and cheese. Revueltas: all three, and the commonest.
Loroco: the Central American flower bud, with cheese. Sold in jars outside El Salvador.
Pupusas de arroz: made with rice flour instead of corn, the speciality of Olocuilta — paler and softer.
Honduras makes them too, and ko.wikipedia describes them as "of El Salvador and Honduras". El Salvador, though, designated the pupusa its national dish by law and made the second Sunday in November the Día Nacional de la Pupusa, which is the basis for the attribution here.

Tips

The answer wrapping and sealing gives is unavailable. That guide says "the pleats are structural — pleating lengthens the seam and builds in slack, and that slack absorbs the expansion during cooking." Masa has no gluten, so it tears instead of stretching and cannot be pleated. A pupusa closes a ball and then flattens it, spreading the seam across the whole disc. Leaving no single point to split is how it is sealed.
Water is both the glue and the lubricant. The same guide says wheat and rice wrappers take water because "surface starch dissolves into paste". Masa is nothing but starch, so its entire surface is glue — which is why the water on your hands seals and stops it sticking at the same time.
The filling escapes at the rim. Leave a centimetre clear. The guide's "nothing sticks to a sealing edge with filling on it" shows up here as a visible failure on the pan.
Arepas do it in the opposite order. An arepa is griddled first and then split and filled, so its dough never has to stretch around anything; a pupusa's has to pass that test. The two flours are not interchangeable either — masarepa is pre-cooked corn flour, while masa harina is ground from corn cooked in lye (pozole).
The hydration is the whole recipe. Cracking means more water; sticking badly to wet hands means more flour. Warm water hydrates the flour more evenly than cold.
Do not oil the pan. Dry is correct: oil fries the surface hard and burns the cheese that escapes.
Curtido is not a garnish, it is the balance. A rich salty filling needs acid and crunch, and after a couple of days it starts to ferment properly and gets better.
