Instructions
Cook the tuna
- Add the tuna steaks to a pie plate or shallow pan.
- Whisk together the rice wine vinegar, soy sauce, sugar, sesame oil, garlic, onion, and ginger.
- Reserve 2 tablespoons of the marinade. Pour the rest over the steaks.
- Marinate for at least 30 minutes and up to 2 hours in the fridge.
- Heat 1 tablespoon olive oil in a skillet over medium-high heat.
- Remove the tuna from the marinade and shake off the excess liquid.
- Sear the tuna in the skillet, turning once, about 2 to 3 minutes per side for very rare.
- Transfer the tuna to a dish and place in the freezer to chill for 5 to 10 minutes. This will make it easier to cut thin slices.
Make garlic cream
- Add the roasted garlic cloves, sour cream, heavy cream, and lemon juice in the bowl of a food processor. Pulse to combine into a smooth cream. The cream should be thin enough to drizzle.
- Season with salt and pepper.
- Pour cream into a squeeze bottle and set aside.
Assemble nachos
The Heart of the Table
Dropping a massive platter of intricately composed tuna nachos into the center of a gathering instantly breaks down the formalities of a traditional dinner party. The shared, hands-on nature of the dish forces guests to interact closely, laughing and reaching over one another, while the intensely high-end ingredients—rare tuna and roasted garlic cream—ensure the experience still feels incredibly luxurious.
Neighborly Grace
- THE PRESENTATION: Do not build this vertically like a mountain; lay the chips out in a wide, expansive single layer on a massive heavy wooden or slate serving board. Ensure every single chip is intentionally loaded with dressed greens and a thin, vibrant slice of rare pink tuna before violently zigzagging the heavy roasted garlic cream across the entire board.
- THE POUR: The intense umami of the soy-ginger marinade, the sharp bite of the vinegar greens, and the heavy richness of the garlic cream demand a wildly crisp, effervescent pour. An icy, bone-dry Champagne or a fiercely sharp, highly carbonated Txakolina cuts straight through the sour cream while complementing the delicate, rare tuna perfectly.
- THE VIBE: High-energy, sophisticated cocktail hours. This is the dish you execute as the sun begins to set over the patio, served alongside heavy crystal coupes of iced champagne, demanding a loud, interactive, and deeply memorable start to the evening.
