Tuna crudo with ruby grapefruit and fennel
"I ate a similar dish to this a few years ago while holidaying in Porto Palo di Menfi in Sicily," says Nigel Ward. "It was at a little family-run joint on the beach and remains one of the most memorable meals of my life. This dish was a virtue of simplicity - just three or four ingredients, at the perfect point in the season: beautiful Mediterranean tuna, bittersweet grapefruit, bitter, peppery oil, and sweet, anise-flavoured fennel."


  • 2 ruby grapefruit, rind finely grated, flesh segmented, catching juice, plus extra squeezed from membrane (you need 60ml)
  • 100 ml extra-virgin olive oil
  • 250 gm sashimi-quality tuna loin (see note)
  • 2 fennel bulbs, shaved on a mandolin and placed in iced water, fronds reserved
  • 3 radishes, cut into thin wedges and placed in iced water
  • 1 tbsp salted capers, soaked in cold water for 5 minutes, then rinsed under cold running water, drained


  • 1
    Combine grapefruit rind and juice with olive oil. Slice tuna as thinly as possible and place on a platter. Season to taste and spoon on a quarter of the dressing, then refrigerate to marinate
    (30 minutes).
  • 2
    To serve, scatter fennel, radish, capers and grapefruit segments over tuna. Dress salad with remaining dressing and scatter with coarsely chopped fennel fronds.


Note Tuna can be substituted with kingfish or swordfish.
