What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use the highest quality, sushi-grade tuna you can find. Since the center is served rare, freshness is paramount.
- 2Ensure your pan is very hot before adding the tuna. A proper sear creates a delicious crust while keeping the inside tender and rare.
- 3Do not move the tuna steaks once they are in the pan. Let them sit undisturbed to form a perfect crust.
- 4A very sharp knife is essential for slicing. A dull knife will tear the delicate fish and ruin the presentation.
- 5This dish is best served immediately after cooking for the ideal texture and temperature contrast.
- 6For an extra layer of flavor, lightly toast the sesame seeds in a dry pan for 2-3 minutes before coating the tuna.
