Ottolenghi's Tonnato Sauce


  • 2 large egg yolks
  • 3 tablespoon fresh lemon juice
  • 1 cup flat-leaf parsley (roughly chopped, about 20 grams)
  • 1 (4 ½ oz) can tuna in oil
  • 1 tablespoon capers (rinsed and drained)
  • 2 oil-packed anchovy filets (rinsed and patted dry)
  • 1 clove garlic (peeled and crushed)
  • 3/4 cup extra-virgin olive oil


Place the egg yolks in the bowl of a food processor along with lemon juice, parsley, tuna, capers, anchovies, and garlic. Blitz for a minute to form a rough paste, scraping down the sides of the bowl with a spatula as needed. With the machine running, slowly add the oil in a slow, steady stream, until the consistency is that of a thin mayonnaise. Set aside.
