I know nothing about making sushi and I have never thought of making it too.
It happens that my mother is making sushi today and there are some leftover sushi rice. So I thought why not try it. An impromptu decision and without any knowledge or any ingredients, I just jump in for the fun of playing around with sushi.
You know what's the quickest way to learn how to make a Tamago Sushi? Search the YouTube! I type in "Tamago Sushi" and several videos are found and I just learn how to make the japanese type of omelette from there.
It's neither nice-looking nor delicious (cos I don't even have some of the ingredients), but it's just for fun! :)
