Potato Masa Tortillas Recipe

Santiago Lastra's ingenious recipe for tortillas made only from mashed potato, potato starch and salt solves the problem of the inaccessibility of freshly cooked and milled dried corn kernels (fresh corn masa) outside of Mexico. “We have developed alternative options with ingredients that are at their best pretty much …

Ingredients
  • 500g of new potatoes
  • 250g of potato starch, plus extra for dusting
  • 5g of fine salt
Method · 1 h 15 min
  1. Place the whole, unpeeled potatoes in a saucepan of cold water, bring to the boil and cook for 20 minutes, then drain and remove the skins whilst hot. Pass the flesh through a ricer, sieve (strainer) or mash with a potato masher to create a smooth paste
  2. Combine all the ingredients in a bowl and mix together with your hands until homogenous (adding a little splash of water if needed)
  3. Cut out 2 squares of baking parchment and dust them with potato starch
  4. Take a piece of masa weighing around 35g between the 2 squares
  5. Press in a tortilla press (or between 2 heavy pans)
  6. Remove the tortilla from the press and remove the baking parchment, then gently reapply it so that the paper is still protecting the tortilla but is not stuck to it. Repeat with the remaining potato masa
  7. Heat a dry frying pan over a medium heat and cook 1 of the tortillas (removing the paper first) for 1 minute until it releases from the pan and moves easily around
  8. Then flip and cook for a further 30-45 seconds
  9. Flip one more time and increase the heat to high – the tortilla will puff up
  10. Once puffed, cook for a further 10 seconds, then remove and wrap in a cloth to keep warm
  11. Repeat with the remaining tortillas and then serve hot

Remember the Mexican rule: ‘a tortilla is only ready after if puffs’. You can make the mashed potato a couple of days in advance and store in the refrigerator.”

This recipe is taken from Mexican Soul: A New Style of Cooking by Santiago Lastra (£30, Quadrille Publishing Ltd). Santiago says: “If you can’t find potato starch, you can make a similar dough with 200g mashed potatoes, 2 tbsp cornflour, 2 tbsp plain flour and 1 tbsp neutral oil.

This version of the dough is not as flexible, so the tortillas might not puff up as much, but they will still be great for making tacos.” Place the whole, unpeeled potatoes in a saucepan of cold water, bring to the boil and cook for 20 minutes, then drain and remove the skins whilst hot.
