Volcano Roll Sushi Recipe

This post may contain affiliate links. Please read my disclosure policy.

This recipe specifically is my personal favorite from Japanese cuisine. It might seem like a regular sushi roll made of seafood, avocado, and cucumber rolled in seaweed sheet and sushi rice. However, the mouse watering, spicy, and delicious crab salad lava-like toppings give this regular sushi a whole new flavor!

Some important tips to consider when cooking this recipe

  • Make sure to get a sushi rolling mat, highly available and very handy when making sushi rolls.
  • Using Japanese short-grain rice is highly recommended in this recipe, giving a more fluffy outcome. Use the High-quality type with a 1:1 ratio with the water to maintain this fluffiness even after its compression in the roll.
  • Using rice vinegar, sugar, and salt can add more flavor to your rice.
  • Make sure you have some Tezu water in a small bowl when rolling the sushi to prevent the rice from sticking to your fingertips. It’s fairly easy to make. You just need to mix 1/4 cup of water and 2 teaspoons rice vinegar together.
  • Squeezing the rolls while and after rolling them gently with your hands prevent the rolls from falling apart.
  • The seafood filling is traditionally composed of crab meat. However, you are free to use imitation crab sticks, shrimp, scallops, even fish such as tuna, salmon, and yellow tail.
  • The spicy, hot, and delicious flavor of the key ingredient in this recipe (the crab salad topping) is obtained from the Sriracha sauce or Sriracha mayo. You can adjust the spiciness to your taste with the amount of Sririacha added. Of course, you can use regular mayo for the non-spicy version of this recipe.
  • You can toast the sesame seeds by adding them to a skillet on a medium flame and leave them to toast for 5 minutes to enhance released flavors.
