Shirayaki Frequently Asked Questions and Useful Information for Travel

What is Shirayaki eel?

Shirayaki eel is prepared by filleting, deboning, butterflying, skewering, and grilling. Unlike kabayaki, shirayaki-style cooking involves roasting the eel without tare sauce, seasoned only with salt, to highlight the genuine flavor of the eel.

Can you eat the bones in unagi?

Yes, the fine, cartilaginous bones in freshwater eel, or unagi, are typically very soft and meant to be eaten along with the flesh rather than picked out. They are often cooked until soft enough to be swallowed without being noticed or can be eaten with minimal chewing, melting in your mouth. In Japan, it's common to eat the entire fish, or the bones are processed into snacks like crispy 'hone senbei' or bone crackers.

What is kabayaki in Japanese?

Kabayaki (蒲焼) is a Japanese preparation of fish, especially unagi eel. The fish is split, gutted, boned, butterflied, cut into fillets, skewered, and dipped in a sweet soy sauce-based marinade before being grilled or griddled.

What kind of fish is unagi?

Unagi (ウナギ) is the Japanese word for freshwater eel, most commonly the Japanese eel, Anguilla japonica (日本鰻, nihon unagi). Unagi is a popular ingredient in Japanese cuisine, frequently prepared as kabayaki.

What are the best ways to experience Shirayaki's unique culinary scene?
