What is a volcano roll?
Known for its unique volcano eruption like appearance, the volcano roll is an inside-out maki roll where the nori seaweed wraps the seafood and vegetable fillings inside, and the sushi rice is on the outside. It’s then topped with a baked spicy and creamy “lava”-like crab salad, making it look like a volcano or lava.
What ingredients go into volcano roll sushi?
The fillings of a volcano roll usually contain seafood (or imitation crab), avocado and cucumber. The toppings are made with seafood and spicy mayo. You can customize it to your favorite fillings and adjust the level of spiciness.
- Seafood: Traditional volcano recipe contains crab meat and other seafood. You can use imitation crab sticks (kanikama), shrimp, scallops, fish such as tuna, salmon, and yellow tail.
- Vegetables: You can use cucumbers or avocado. If you use American cucumber, make sure to remove the seeds as they contain too much water.
- Nori (Seaweed Sheets)
- Sushi Rice: I recommend using Japanese short grain rice for the best fluffy rice. To add some flavors to your rice, you can season it with a small amount of rice vinegar, sugar and salt.
- Spicy Mayo: You can make your own spicy mayo by combining Sriracha sauce and mayo.
- Masago or tobiko (optional)
Pro Tip: You’ll also need a sushi rolling mat to assemble the sushi. It’s fairly inexpensive, and you can buy it at Asian supermarkets or online.
How to make a volcano roll
The volcano roll has a show-stopping impressive look, but it’s easier than you think with a few simple tips:
Cooking sushi rice
The best rice for sushi rolls is high-quality short grain sushi rice. It uses less water than regular steamed rice. A 1:1 ratio is great for making sushi rolls so the rice can stay fluffy even after being pressed tightly.
Pro tips: To prevent rice from sticking to your hands, use Tezu to wet your hands when handling rice. It’s a hand dipping liquid made with 1/4 cup water and 2 teaspoons rice vinegar.
How to make the crab salad topping
A creamy and spicy crab salad topping is key to this recipe:
- First cut imitation crab (kanikam) and shrimp into small chunks.
- Add them to a mixing bowl, and season with salt, pepper, and spicy mayo.
- Place the mixture to a baking pan, and bake at 400°F for 10-15 minutes.
Pro Tips: The heat comes from Sriracha sauce or Sriracha mayo, and you can adjust the amount to make your rolls more or less spicy. You can also use regular mayo for a non-spicy version.
Making the volcano roll
- First pat down a thin layer of cooked rice over half of the nori seaweed sheet. Sprinkle with optional sesame seeds. Then flip the rice covered nori sheet so that the rice is facing down.
- Place the fillings on top of the nori, and start rolling using a bamboo mat. Apply some pressure while rolling to tighten it up. Once the roll is complete, you can move it to the cutting board and cut them into pieces.
- Arrange about 8 sushi pieces on a plate, and top them with the freshly baked crab salad topping. You can drizzle some spicy mayo and sprinkle optional tobiko or masago on top.
Pro tip: To prevent sushi rolls from falling apart, you’ll need to squeeze the roll gently while rolling. Once you finish, you can place the bamboo mat over the sushi roll and gently squeeze the roll again.
