Ingredients

• 1 full sheet of nori, 19 by 21 centimeter
• 180 gram cooked Koshihikari short-grain rice
• 30 milliliter rice vinegar
• 12 gram sugar
• 6 gram salt
• 80 gram kanikama (Japanese imitation crab sticks), shredded by hand
• 40 gram just-ripe Hass avocado, 1-centimeter sticks
• 40 gram Japanese cucumber, 1-centimeter sticks
• 1 teaspoon mixed toasted black and white sesame seeds
• 100 gram raw sea scallop, U-slash-10 dry-pack, hand-diced into 5-millimeter cubes
• 50 gram additional kanikama or Dungeness crab, chopped
• 60 gram Kewpie Japanese mayonnaise
• 15 gram Huy Fong sriracha (1 tablespoon)
• 10 gram orange tobiko
• 5 gram masago
• 1 thinly-sliced green onion
• 30 milliliter unagi kabayaki sauce (sweet eel sauce)
• 60 milliliter mirin (for unagi sauce)
• 60 milliliter soy sauce (for unagi sauce)
• 30 gram sugar (for unagi sauce)

Instructions

1. Season 180 gram cooked Koshihikari short-grain rice with 30 milliliter rice vinegar, 12 gram sugar, and 6 gram salt, then fan to body temperature.
2. Shred 80 gram kanikama by hand. Cut 40 gram Hass avocado and 40 gram Japanese cucumber into 1-centimeter sticks.
3. Prepare the unagi kabayaki sauce: Reduce 60 milliliter mirin, 60 milliliter soy sauce, and 30 gram sugar for 8 minutes to yield 30 milliliter sauce.
4. Prepare the volcano topping: Hand-dice 100 gram raw sea scallop into 5-millimeter cubes. Chop 50 gram additional kanikama or Dungeness crab. Thinly slice 1 green onion.
5. In a small bowl, gently fold together the diced scallop, chopped crab, 60 gram Kewpie Japanese mayonnaise, 15 gram Huy Fong sriracha, a portion of 10 gram orange tobiko, 5 gram masago, and a portion of the sliced green onion until salmon-pink and glossy.
6. Wrap a bamboo makisu rolling mat in plastic wrap. Lay 1 full sheet of nori, glossy side down, on the mat.
7. Spread the 180 gram seasoned rice evenly edge-to-edge over the nori. Sprinkle a portion of 1 teaspoon mixed toasted black and white sesame seeds over the rice.
8. Flip the nori and rice so the rice faces down on the mat and the nori faces up.
9. Lay the shredded kanikama, avocado sticks, and cucumber sticks in a single line across the center of the nori.
10. Roll the sushi inside-out: Lift the bottom edge of the mat with your thumb, tuck tightly, and continue rolling away from you with gentle pressure, ensuring the seam is down.
11. Slice the roll into 8 equal pieces with a wet, sharp yanagiba, wiping the blade between cuts.
12. Arrange the 8 pieces in a curving line on an oven-safe slate or shallow stoneware plate.
13. Generously mound the volcano topping over the top of all 8 pieces.
14. Preheat your oven to 425°F (218°C).
15. Bake on the upper-middle rack for 6 minutes until the topping is bubbling vigorously and the edges have just started turning golden-brown.
16. Optionally, torch the entire surface for exactly 5 seconds with a kitchen torch from about 10 centimeter distance for a crisp caramelized surface.
17. While still bubbling hot, drizzle 30 milliliter of the glossy mahogany unagi kabayaki sauce back and forth across all 8 pieces in a generous zigzag pattern.
18. Sprinkle any remaining toasted sesame seeds. Add an extra small crown of the remaining orange tobiko on each piece. Scatter the rest of the sliced green scallion across the top.
19. Serve immediately while the topping is still bubbling and the cool rice underneath is just barely warm.

Frequently asked questions

What is a Volcano Roll?

The Volcano Roll is a SoCal fusion sushi invention with a California Roll base topped with a molten, spicy seafood mixture. It emerged in Orange County sushi bars around 1995 as a way to serve warm, cooked sushi, catering to those who prefer cooked seafood.

What ingredients are in a Volcano Roll's topping?

The 'dynamite' topping includes hand-diced raw sea scallop, additional chopped kanikama or Dungeness crab, Kewpie Japanese mayonnaise, Huy Fong sriracha, orange tobiko, masago for textural pop, and thinly-sliced green onion. These are gently folded together to create a salmon-pink mixture.

Why is Kewpie mayonnaise recommended for the Volcano Roll?

Kewpie mayonnaise is crucial because it uses only egg yolks, no water, and a touch of MSG, ensuring it stays rich and stable when baked. This composition allows it to brown beautifully and stabilize into a glossy, creamy glaze, unlike regular American mayonnaise which can split.

What is the baking temperature and time for a Volcano Roll?

The Volcano Roll should be baked at 425°F (218°C) for exactly 6 minutes on the upper-middle rack. This temperature ensures the Kewpie mayonnaise achieves its desired texture and the diced raw scallop cooks fully to 145°F (63°C) without becoming rubbery.

How is unagi kabayaki sauce made for the Volcano Roll?

The unagi kabayaki sauce is a sweet eel sauce, prepared by reducing 60 milliliter mirin, 60 milliliter soy sauce, and 30 gram sugar for 8 minutes. This yields 30 milliliter of glossy mahogany sauce that is drizzled over the hot Volcano Roll.
