Pupusas (Salvadoran pupusas)

Instructions

1. In a bowl, mix the masa harina with the salt. Gradually pour in the warm water, kneading until you have a soft dough that no longer sticks to your fingers, about 5 minutes.
2. Cover the dough with a damp cloth and leave to rest for 10 minutes so the flour hydrates.
3. Roughly mash the red beans with a fork together with the garlic and onion, then add the cumin and pepper to make a rustic purée.
4. Divide the dough into 12 balls. Flatten each ball in the palm of your hand into a disc, then make a hollow in the centre and fill it with a spoonful of beans and a little cheese.
5. Close the dough over the filling and gently flatten into a cake about 1 cm thick, making sure the filling doesn't escape.
6. Heat a frying pan or cast-iron griddle over medium heat and lightly grease it. Cook the pupusas for 3 to 4 minutes on each side, until golden in places.
7. Serve piping hot with the curtido and tomato sauce.
