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 (imitation crab sticks), shredded by hand
• 40 gram Hass avocado, in 1-centimeter sticks
• 40 gram Japanese cucumber, in 1-centimeter sticks
• 1 teaspoon mixed toasted black and white sesame seed
• 100 gram raw sea scallop, sustainable U-slash-10 dry-pack, hand-diced into 5-millimeter cubes
• 50 gram additional kanikama or real Dungeness crab, chopped
• 60 gram Kewpie Japanese mayonnaise
• 15 gram Huy Fong sriracha (about 1 tablespoon)
• 10 gram orange tobiko
• 5 gram masago
• 1 thinly-sliced green onion
• 30 milliliter glossy mahogany unagi kabayaki sauce
• Remaining toasted black and white sesame seed
• Extra small crown of jewel-bright orange tobiko
• Rest of the sliced green scallion

Instructions

1. Prepare sushi rice: Cook Koshihikari short-grain rice. Season with 30 milliliter rice vinegar, 12 gram sugar, and 6 gram salt, then fan to body temperature.
2. Prepare California Roll filling: Shred 80 gram kanikama by hand. Cut 40 gram Hass avocado and 40 gram Japanese cucumber into 1-centimeter sticks.
3. Prepare volcano topping: In a small bowl, gently fold together 100 gram hand-diced raw sea scallop, 50 gram chopped additional kanikama (or Dungeness crab), 60 gram Kewpie Japanese mayonnaise, 15 gram Huy Fong sriracha, 10 gram orange tobiko, 5 gram masago, and 1 thinly-sliced green onion until salmon-pink and glossy.
4. Assemble California Roll: Wrap a bamboo makisu in plastic wrap. Place nori (glossy side down) on the mat. Spread 180 grams of rice edge-to-edge over the nori. Sprinkle 1 teaspoon mixed toasted black and white sesame seed on top of the rice. Flip the nori so the rice faces down on the mat and nori faces up.
5. Fill and roll: Lay the kanikama strands, avocado sticks, and cucumber sticks in a single line across the center of the nori. Lift the bottom edge of the mat with your thumb, tuck tight, and continue rolling away from you with gentle pressure, seam down, to form an inside-out uramaki.
6. Slice and arrange: Slice the roll into 8 equal pieces with a wet, sharp yanagiba, wiping the blade between cuts. Arrange the 8 pieces in a curving line on an oven-safe slate or shallow stoneware plate.
7. Apply topping: Mound the volcano topping generously over the top of all 8 pieces.
8. Bake: Preheat oven to 425°F (218°C), using convection if available. Bake on the upper-middle rack for 6 minutes until the topping is bubbling vigorously and the edges turn golden-brown.
9. Torch (optional): For 5 seconds, torch the entire surface with a kitchen torch from about 10 centimeter distance to add a crisp caramelized surface.
10. Finish and serve: While still bubbling hot, drizzle 30 milliliter of glossy mahogany unagi kabayaki sauce in a generous zigzag pattern across all 8 pieces. Sprinkle remaining toasted sesame, add an extra small crown of orange tobiko on each piece, and scatter the rest of the sliced green scallion across the top. Serve immediately.

• The Volcano Roll is a 100% SoCal fusion sushi invention, created for customers who preferred cooked and warm sushi.
• It originated in Orange County sushi bars around 1995 and had spread to virtually every American sushi restaurant by 2000.
• The base consists of an inside-out California Roll with nori, Koshihikari rice, kanikama crab, avocado, and cucumber filling.
• The 'dynamite' topping is made from hand-diced raw sea scallop, additional kanikama, Kewpie Japanese mayonnaise, sriracha, tobiko, masago, and green onion.
• Kewpie mayonnaise is crucial because its all-yolk, no-water, MSG-enhanced formula remains rich and stable when baked at 425°F, unlike regular American mayonnaise.
• The roll is baked at 425°F (218°C) for 6 minutes, which perfectly browns the Kewpie mayo and cooks the scallop to an internal temperature of 145°F (63°C).
• An optional but recommended step involves torching the surface for exactly 5 seconds to achieve a crisp caramelized texture.
• Final plating includes a generous zigzag drizzle of glossy unagi kabayaki eel sauce, extra orange tobiko, and scattered green scallions.
• One Volcano Roll yields 8 pieces and is intended to serve 2 people.
• The Volcano Roll is recognized as one of the top-15-selling sushi rolls in U.S. casual dining today.

Frequently asked questions

What is the Volcano Roll?

The Volcano Roll is a SoCal fusion sushi creation featuring an inside-out California Roll topped with a baked mixture of spicy seafood, primarily chopped scallops and imitation crab, and Kewpie mayonnaise. It was invented in Orange County in the mid-1990s as a cooked alternative to traditional raw fish sushi.

What are the key ingredients in a Volcano Roll?

Key ingredients include a California Roll base with nori, Koshihikari rice, kanikama, avocado, and cucumber. The 'dynamite' topping features raw sea scallop, more kanikama, Kewpie mayonnaise, sriracha, tobiko, masago, and green onion.

Why is Kewpie mayonnaise recommended for the Volcano Roll topping?

Kewpie mayonnaise is recommended because it uses only egg yolks, no water, and contains MSG, allowing it to brown beautifully and remain rich and stable when baked at 425°F. Regular American mayonnaise can split and weep under the same conditions.

How long and at what temperature is the Volcano Roll baked?

The Volcano Roll is baked at 425°F (218°C), preferably with convection, for exactly 6 minutes. This temperature and time ensure the topping bubbles, turns golden, and the scallops cook to 145°F (63°C) without becoming rubbery.

Where did the Volcano Roll originate?

The Volcano Roll emerged in Orange County sushi bars around 1995. While the exact origin is disputed, Hama Sushi in Newport Beach, Sushi Roku in Hollywood, and several Newport and Costa Mesa establishments all claim early versions.
