For the Spicy Mayo

80 g Japanese mayonnaise
15 g gochugaru Korean chili flakes
10 ml sriracha sauce
5 ml fresh lime juice
3 g garlic minced

For the Toppings

200 g Persian cucumber julienned
160 g carrots shredded

240 g ripe avocado sliced
20 g pickled ginger
10 g scallions thinly sliced
8 g nori sheets cut into thin strips

Method

Prepare the Seasoned Sushi Rice

Rinse 300g sushi rice under cold water 4–6 times, until the water runs almost clear. Combine the rinsed rice with 480ml water in a medium saucepan. Bring to a boil, then reduce to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Transfer the rice to a large bowl and gently fold in 45ml rice vinegar, 15g sugar, and 7g salt while still warm. Spread on a baking sheet to cool to room temperature, fanning occasionally.

Prepare the Tuna

Pat 600g sushi-grade tuna steaks completely dry with paper towels. Season both sides generously with 4g salt and 2g black pepper. Press 40g mixed sesame seeds (white and black) onto all surfaces of the tuna, creating an even crust.

Make the Spicy Mayo

In a small bowl, whisk together 80g mayonnaise, 15g gochugaru (Korean chili flakes), 10ml sriracha sauce, 5ml lime juice, and 3g minced garlic until smooth. Adjust heat level to taste and set aside.

Sear the Tuna

Heat 20ml neutral oil in a heavy skillet over high heat until shimmering. Sear tuna for 45-60 seconds per side for rare, or 90 seconds per side for medium-rare. The sesame crust should be golden and the center still pink. Remove from heat and let rest 2 minutes, then slice against the grain into 1cm thick pieces.

Assemble the Bowls

Divide cooled sushi rice among four bowls (approximately 200g per bowl). Arrange sliced tuna on top of each rice portion. Add 200g julienned cucumber, 160g shredded carrots, 120g edamame, and 240g sliced avocado around the tuna.

Garnish and Serve

Drizzle each bowl with the spicy mayo sauce (about 25g per serving). Garnish with 20g pickled ginger, 10g sliced scallions, 8g toasted nori strips, and 5g toasted sesame seeds. Serve immediately with additional soy sauce on the side if desired.

Notes

- Ensure your tuna is labeled sushi-grade or sashimi-grade from a reputable fishmonger, as it will be served rare to medium-rare. If you cannot source sushi-grade tuna, substitute with cooked salmon or shrimp.

- The key to perfect seared tuna is a screaming hot pan and completely dry fish. Any moisture will prevent proper browning and crust formation. Don't move the tuna once it hits the pan.

- This bowl is highly customizable - swap vegetables based on preference or availability. Try adding mango, radishes, or snap peas. The spicy mayo can be made up to 3 days ahead and stored refrigerated.
