To make nachos, pour 10.5 oz (300 g) of corn flour into a bowl, add salt, and gradually add water, stirring to absorb it gradually. Don't add all the water at once, as you may need less (it depends on how fine your corn flour is). At first, the mixture will be crumbly, but it will then solidify into a compact dough.
It will take about 10 minutes to obtain a dough that can be shaped by hand; the consistency will resemble plasticine, so it will no longer crumble. Using coarse-grained flour would have taken more time to obtain a dough that can be shaped. Let it rest for 20 minutes at room temperature.
If you want to season your nachos with cumin, coriander, or other spices, this is the time to do it: pour 2.6 oz (75 g) of corn flour into a bowl, add finely chopped spices, mix together, and set aside.
To make perfectly triangular, thin, and crispy nachos, take a small amount of dough and place it on a sheet of parchment paper. Then place another sheet of parchment paper on top and roll the dough with a rolling pin until you get a very thin sheet. The goal is to reach just 2 millimeters in thickness.
Once the nacho dough is rolled out, we can remove the top layer of parchment paper and sprinkle the reserved spicy cornmeal on top. Make sure that the entire surface of the dough is covered with the spicy cornmeal. Then, use a rolling pin to press the cornmeal into the dough and to roll it out even further.
Using a 15 cm bowl or cookie cutter, cut the dough into a circle. Using a knife, cut the circle into 4 equal parts, then cut those parts in half, resulting in 8 equal triangles (in other words, make two intersecting X's through the center).
Once the nacho triangles are formed, we can sprinkle them with the remaining spicy flour on the side that has not yet been floured to prevent sticking. Repeat this process of rolling and cutting the dough until it is all used up.
