📖 Instructions

1. Prepare the Tuna: Pat the Ahi tuna steaks dry with paper towels. This step is crutial for achieving a good sear. Moisture is the enemy of a good crust!
2. Season Generously: Sprinkle both sides of the tuna steaks with sesame seeds, freshly ground black pepper, and a pinch of sea salt. Don't be shy with the seasoning; it's what gives the tuna its flavor crust.
3. Make the Ponzu Sauce: In a small bowl, whisk together soy sauce, rice vinegar, lime juice, and a dash of sesame oil. Taste and adjust the seasoning as needed. Some people like it sweeter, some more tart. It’s all about personal preference! Also, you can add some chilli flakes, it is delicious.
4. Heat the Pan: Place a cast-iron skillet or heavy-bottomed pan over high heat. Add high-heat cooking oil, such as avocado or grapeseed oil. Let the pan get smoking hot. The pan should be hot enough that a drop of water sizzles immediately.
5. Sear the Tuna: Carefully place the seasoned tuna steaks into the hot pan, ensuring they aren't overcrowded. Sear for about 1-2 minutes per side for rare, or slightly longer if you prefer it more well-done. Use tongs to carefully flip the steaks.
6. Achieve the Perfect Sear: Aim for a beautiful golden-brown crust on each side. The center should still be mostly raw. If you're unsure, use a meat thermometer to check the internal temperature. For rare, aim for 115-125°F (46-52°C).
7. Rest Briefly: Remove the seared tuna steaks from the pan and place them on a cutting board. Let them rest for a minute or two. This allows the juices to redistribute, resulting in a more tender and flavorful tuna steak.
8. Slice and Serve: Using a sharp knife, slice the tuna steaks against the grain into thin slices, about 1/4 inch thick. This makes them easier to eat and enhances the texture.
9. Plate and Drizzle: Arrange the sliced tuna on a serving plate. Drizzle generously with the prepared ponzu sauce. Garnish with thinly sliced green onions and extra sesame seeds, if desired.
10. Serve Immediately: Seared Ahi tuna is best served immediately. Enjoy it as an appetizer, a light meal, or as part of a sushi bowl. It pairs beautifully with a side of steamed rice or a fresh salad.
