Prepare sushi rice according to your chosen sushi recipe, ensuring it is seasoned with sushi vinegar to achieve the right flavor.
Lay a nori sheet on your bamboo sushi mat and spread an even layer of rice over it, leaving a small border at the top.
Add your fillings of shrimp tempura, cucumber, and eel in a line across the center of the rice.
Gently lift the bamboo mat and begin rolling the sushi away from you, pressing lightly to maintain a firm and even shape.
Once you reach the exposed edge of the nori, moisten it with a little water to help seal the roll.
"Carefully roll it to completion, and with a sharp knife, slice the roll into bite-sized pieces.
Top with sliced avocado and tobiko. Sprinkle with black sesame seeds
