Spicy scallop, sauce, masago, onion
In a bowl, combine the chopped scallops, Sriracha sauce, mayonnaise, and chopped green onions. Mix well until the scallops are evenly coated.
Lay a nori sheet on a bamboo sushi mat or a flat surface, shiny side down.
Wet your hands and grab a handful of sushi rice. Spread it evenly over the nori, leaving about an inch at the top edge.
Place a portion of the spicy scallop mixture along the bottom edge of the rice-covered nori.
Sprinkle masago on top of the scallop mixture for added flavor and texture.
Starting from the bottom edge, roll the nori tightly over the filling. Use the sushi mat to help shape and compress the roll. Seal the edge with a little water.
Cut the hand roll in half if desired, and serve with soy sauce for dipping.
