Ingredients for 4

  • Tortilla
  • 600 g Maris Piper potatoes , peeled and sliced 3mm thick
  • 8 free-range eggs , beaten
  • 250 ml extra virgin olive oil , for confiting
  • 1 pinch smoked sea salt
  • Caramelised onions
  • 3 large onions , thinly sliced
  • 30 g butter
  • 1 tsp sherry vinegar
  • 1 tbsp chives , snipped, to serve

Method

  1. Melt the butter in a wide pan and cook the onions very slowly over a low heat for 30 to 40 minutes until deep golden and jammy, finishing with the sherry vinegar.
  2. Meanwhile, heat the olive oil in a deep pan and confit the potatoes over a low heat for 20 minutes until tender, then drain well, reserving the oil.
  3. Fold the warm potatoes and half the caramelised onions into the beaten eggs, season with smoked sea salt and rest for 10 minutes.
  4. Heat a tablespoon of the reserved oil in a 24cm non-stick pan to medium, pour in the mixture and cook for 4 minutes, swirling, until the edges set.
  5. Flip onto a plate and slide back into the pan, then cook for just 2 to 3 minutes so the centre stays soft and almost runny.
  6. Slide onto a board, top with the remaining onions and the chives, and rest for 5 minutes before cutting into thick wedges.
