. Prepare Sushi Rice:

Rinse 2 cups of sushi rice under cold water until the water runs clear.

Cook the rice according to package instructions.

While the rice is still warm, gently fold in 1/3 cup of sushi vinegar to season. Allow it to cool to room temperature.

Assemble Ingredients:

Place a bamboo sushi rolling mat on a clean surface and cover it with plastic wrap. Put a sheet of nori, shiny side down, on the mat.

Wet your hands to prevent the rice from sticking, then spread an even layer of sushi rice over the nori, leaving a small border at the top.

Add Fillings:

Arrange a handful of shredded imitation crab, avocado slices, and julienned cucumber along the bottom edge of the rice.

Roll the Sushi:

Using the bamboo mat, roll the sushi away from you, starting at the bottom. Apply gentle pressure to shape the roll.

Moisten the top border of the nori with water to seal the edge.

Slice the Roll:

Using a sharp knife, wet it to prevent sticking, then slice the roll into bite-sized pieces.

Spicy Tuna Roll Variation:

For a Spicy Tuna Roll, mix diced raw tuna with spicy mayo (mayonnaise and sriracha) and use it as a filling. You can also add cucumber or avocado for extra freshness.

Serve and Enjoy:

Arrange the California rolls on a plate with pickled ginger and wasabi.

Serve with soy sauce for dipping.
