Not all sushi is made out of fish. One classic example of fish-free sushi is the tamago nigiri. You can find this selection at pretty much any place that serves sushi, our Bothell Japanese restaurant included. A significant part of the sushi art, it has historically been believed that a good tamago is one of the best signs of a good sushi chef.
Tamago is a kind of Japanese omelette, made by mixing eggs with ingredients that might include sugar, rice vinegar, soy sauce, or even sake. As the chef prepares this omelette, it is folded over upon itself many times until it takes the shape of many thin layers of egg. The end result has a fascinating texture and a sweet taste, and makes for an excellent choice on any sushi outing.
