  • 1 Heat the reserved 15ml oil in a 20cm frying pan over medium heat and pour in all the egg mixture.
  • 2 Cook for 1 minute, drawing the edges inward with a spatula, then cover and cook over low heat for 4 minutes.
  • 3 Turn off the heat, cover with a flat plate larger than the pan, invert, then slide the tortilla back into the pan.
  • 4 Cook over low heat for another 4–5 minutes, confirm that the centre stays at 75°C for 1 minute, and transfer to a plate.

Ready when

It is ready when the centre does not run and the egg surrounding the potatoes is set but moist.

Caution

Turn off the heat before flipping, and take care that hot oil does not drip from the edge of the plate.
