For this salad, I like to leave the potato skins on for colour and taste. Double the potato recipe for a larger feast, which also helps you use up more of the ‘mahonesa’.

Cook's notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.


Sitting time: 20 minutes

  1. Heat the raisins and sherry vinegar in a small saucepan over medium heat for 2–3 minutes. Set aside.
  2. To make the mahonesa, place the egg yolk and egg in a mixing bowl or in the bowl of a food processor. Whisk or blitz to combine, then incorporate the vinegar, lemon juice and salt. Whisking or blitzing continuously, very gradually pour in the oils, one at a time, in a thin, steady stream, until you have a thick mayonnaise.
  3. Place the potatoes in a large saucepan of salted water and bring to the boil. Cook for 25–30 minutes, until tender but not falling apart.
  4. Drain and transfer to a large bowl with the oil and vinegared raisins and their juice. Stir well to coat the potatoes, then set aside for 20 minutes or so before adding the remaining ingredients and mixing through as much mahonesa as you like. Sprinkle with a few extra tarragon leaves and serve.
