Tortilla de maíz

The ancient Mesoamerican corn flatbread: made by nixtamal, the transformative lime-and-ash process that unlocks corn's full nutrition and gives masa its unmistakable flavour

Origin: Mexico

From the journey of Corn.

The corn tortilla is one of humanity's oldest continuously made foods, with a preparation lineage stretching back 7,000 years. Its secret is nixtamalisation, soaking dried corn in an alkaline solution of slaked lime (cal) and water, a process developed by Mesoamerican peoples that breaks down the corn's pericarp, releases bound niacin, and creates masa: a pliable, earthy dough unlike anything flour or plain ground corn produces. Without nixtamalisation, corn cannot sustain human life as a staple food; the process was one of the great nutritional discoveries in culinary history. Every taco, enchilada, tamale, and tlayuda descends from this single technique.

Ingredients

  • 300 g masa harina (nixtamalised corn flour)
  • 350 ml warm water
  • 0.5 tsp fine salt

Method

  1. Combine masa harina, salt, and warm water in a bowl. Mix thoroughly with your hands until a smooth, slightly tacky dough forms; like soft Play-Doh. It should not crack at the edges when pressed. Add water a tablespoon at a time if too dry; add masa harina if too wet.
  2. Divide the dough into 12 equal balls (about 35g each). Cover with a damp cloth and rest for 10 minutes.
  3. Heat a dry comal, cast iron pan, or heavy skillet over high heat until very hot; a drop of water should evaporate instantly.
  4. Line a tortilla press (or use two cutting boards) with two squares of plastic wrap or a zip-lock bag cut open. Place a dough ball in the centre and press firmly to a 15–16cm disc, about 2mm thick.
  5. Cook each tortilla for 45–60 seconds on the first side, until the edges look dry and it releases easily. Flip and cook 45 seconds. Flip once more and press lightly with a cloth; the tortilla should puff up slightly. Total cook time: about 2.5 minutes.
  6. Stack finished tortillas in a clean cloth or tortilla warmer to keep soft and steamy. Serve immediately, or reheat briefly on the comal.

Notes

Masa harina (brands: Maseca, Bob's Red Mill, Masienda) is dried nixtamalised corn flour: a pantry shortcut that gives excellent results. True masa from freshly nixtamalised corn is sublime but requires planning. The tortilla should smell of corn, lime, and faint earthiness. Tortillas improve dramatically with a very hot cooking surface: an underheated pan produces pale, doughy results.
