To start this recipe for Salvadoran pupusas, you can combine the masa harina and fine salt in a large mixing bowl.
Next, add the 1 ½ cups of water into the dry mixture. Use a spoon to mix the ingredients together. Then slowly add the rest of the water, if needed all of it.
Mix everything well together until the dough has a strong texture. start kneading to ensure the dough is soft and doesn't break when you knead it. Keep kneading and if necessary add a few tbsp of water to the dough until it is smooth, well combined, and easy to form.
Next, you can start shaping the pupusas. Divide the dough into roughly 2-inch balls. Then, use your palms to flatten them into a disc.
Lay the pupusas on a surface and add a tablespoon or two of grated cheese in the center and top it up wit a few pieces of Jalapeño Pepper. Then, pinch the sides closed to form a filled ball of dough again. Using your palms, flatten the cheese-filled ball into a disc.
Next, preheat a skillet and brush it with some vegetable oil. Once heated, place the pupusas in the hot pan. Cook them for roughly 5-10 minutes on each side, or until they start charring.
Place them on some paper towel to drain any excess oil and serve them immediately.
