Ikura（Salmon roe） is a Russian word meaning fish roe. When a skin of sack that holds eggs becomes thinner, eggs are removed and dipped in sweet soy sauce. A fine flavor and umami extract spread and melt in the mouth. It is soaked in a marinade, so it is not necessary to dip it in soy sauce when eaten. Usually it is eaten as Gunkan maki.
