Chikuwa

Chikuwa (竹輪^?) is a Japanese tube-like food product made from ingredients such as fish surimi, salt, sugar, starch, monosodium glutamate and egg white. After mixing them well, they are wrapped around a bamboo or metal stick and steamed or broiled. 

The word chikuwa, ("bamboo ring") comes from the shape when it is sliced.

As it is cheap and a relatively low-fat source of protein, chikuwa is popular as a snack.

In Tottori, the per-household consumption has been the highest of all prefectures for the past 30 years, since the first year such records were kept.
 
There are several regional varieties. In the east part of Tottori and part of Nagasaki, tofu chikuwa is produced that adds tofu to surimi. Often, firm tofu is the preferred selection.

In Yawatahama, Ehime, Kawa-chikuwa (literally skin chikuwa) is produced, which uses fish skin wrap around the skewers and broiled. This is a by-product of regular chikuwa, however texture and taste are different.

In Shikokuchūō, Ehime, there is Ebi-chikuwa, which contains shrimp paste in surimi.

In Komatsushima, Tokushima, there is Take chikuwa (literally bamboo chikuwa), which remains on the bamboo after it is broiled.

Australian sushi restaurants may stuff the hollow with cheese, (processed or soft cheeses like Brie) and deep-fry them in tempura batter.
