Ingredients
Method
Prepare the swordfish
- Place the swordfish fillet on a clean cutting board. If it feels soft, wrap it in plastic wrap and freeze for 20 minutes until firm but not frozen solid.
- Using a long sharp knife, slice the swordfish across the grain into pieces 2-3 mm thick. Work in long, single strokes rather than sawing to keep the slices clean.
- Arrange the slices in a single, slightly overlapping layer across four chilled flat plates.
Make the dressing
- In a small bowl, whisk together the lemon juice and olive oil until lightly emulsified. Season with the sea salt and a few grinds of black pepper.
- Drain the soaked red onion slices and pat dry on a paper towel.
Dress and serve
- Spoon the lemon and olive oil dressing evenly over the swordfish slices on each plate.
- Scatter the rinsed capers, drained red onion slices, and chopped parsley over the fish.
- Finish with the lemon zest if using, and a final light drizzle of olive oil.
- Leave the plates to rest for 5 to 10 minutes at room temperature so the lemon gently firms the surface of the fish, then serve immediately.
Notes
The entire dish rests on fish quality. If your fishmonger cannot confirm same-day delivery or sushi-grade sourcing, choose a different protein rather than compromising.
