What primary seafood ingredient is featured in the "Dynamite Roll"?

The "Dynamite Roll" is a popular sushi roll that traditionally features shrimp as a key ingredient. This roll is often highlighted for its combination of flavors and textures, and prawns, specifically, are typically used in its preparation. The prawns are usually tempura-fried, providing a crunchy texture that contrasts well with the soft sushi rice and other components.

Additionally, while other options like marinated Ahi tuna, snow crab, and avocado may be ingredients found in different types of sushi or rolls, they do not define the Dynamite Roll. The emphasis on prawns in this context makes it the primary seafood ingredient, aligning with common interpretations of this dish across various sushi establishments.
