Red caviar is a caviar made from the roe of Pacific, Atlantic and river species of salmon. Given its high price in the West, red caviar is associated with luxury and wealth, but in Russia and Japan, caviar is commonly served at holiday feasts, weddings and other festive occasions. In Japan, salmon roe is known as ikura (イクラ), which is the transliteration of the Russian word for caviar -- икра (ik-ra), and is commonly eaten in sushi rolls or as a topping on rice. It is considered a common, everyday food, not a luxury item, and is readily available in supermarkets and convenience stores. In Russia red caviar is usually eaten with blini or in sandwiches with white bread, butter and red caviar. The largest red caviar is from Chinook (6–8 mm) and the smallest is from salar (2–2.5 mm). In Alaska, red caviar is also known as salmon caviar or salmon roe.
