List of Shellfish (Kai)

Shellfish has been a traditional sushi topping started off with the origin of Edomae sushi. Its distinctive texture is fascinating, but the thing is, all kinds are expensive. As a sushi topping, it is placed between rich and light in flavor, and functions as a palate refresher.

The texture, flavor and fragrance differ greatly depending on the type and most people either love or hate Shellfish toppings. They include a large volume of umami components, such as Succinic acid. Kai is another topping type that has been eaten as Nigiri sushi since it was invented. Hamaguri is essentially a type of shellfish, but when in the Nigiri sushi world, it is generally lightly seared and then marinated in broth, so it is classified as Nimono.

  1. I realized more a new challenge on this weight loss issue. A single issue is a good nutrition is extremely vital if dieting. A big reduction in fast foods, sugary meals, fried foods, sugary foods, pork, and white colored flour products may be necessary. Having wastes unwanted organisms, and contaminants may prevent objectives for fat-loss. While certain drugs briefly solve the condition, the unpleasant side effects will not be worth it, and so they never give more than a non permanent solution. This is a known proven fact that 95 of celebrity diets fail. Many thanks for sharing your ideas on this site.
