What holds everything together in a Roll of Sushi?

The key ingredient holding everything together in a roll of sushi is sticky rice. Here's why:

* Sushi rice is cooked with a special vinegar mixture. This mixture contains sugar, salt, and rice vinegar. The vinegar makes the rice sticky, allowing it to adhere to itself and the other ingredients in the roll.

* The rice is pressed together firmly. Once the rice is spread on the nori seaweed, it is pressed firmly with your hands to make a compact base for the roll.

* The nori seaweed acts as a wrapper. The nori's natural adhesiveness also helps hold the roll together.

So, it's a combination of sticky rice, the pressure applied during rolling, and the nori's adhesive properties that create a cohesive and delicious sushi roll!
