What Exactly Is Caviar? Caviar is a delicacy made from the roe of sturgeon, also known as a member of the family Acipenseridae. This is a crucial distinction; while fish eggs are roe, only sturgeon roe can be called caviar. Where Does Caviar Originate? Caviar of the highest quality must be sourced from superior sturgeon.
These fish are typically found in particular regions of Italy, Asia, and the region surrounding the Caspian Sea. The caviar pearls are then sorted by size and color and cleaned and rinsed as part of the preparation process. A crucial step is the salt-curing process, which helps to maintain optimal flavor and freshness.
Once the curing process is complete, the eggs are referred to as caviar rather than roe. On the other hand, fish roe can be obtained from fish from all over the world. These eggs may be consumed similarly to caviar. The roe may be salted-cured like caviar (but will not be called caviar) or uncured (which is sometimes called “green eggs” by those in the industry).

Instead, they are commonly regarded as a substitute of inferior quality for caviar. How can I tell if I am purchasing authentic caviar?

Tobiko (flying fish roe) – Among the different varieties, tobiko, flying fish roe, is perhaps the most well-known. The naturally red-orange eggs range in size from 0.5 to 0.8 millimeters and have a mild smoky or salty flavor with a hint of sweetness and a particularly crunchy texture.
Tobiko’s color and flavor can be altered by infusing it with other natural ingredients. Common variations include squid ink for a black hue, yuzu for a yellow hue, beet for a red hue, and wasabi for a green hue. In addition to being used to decorate maki rolls (such as the California), tobiko is frequently served as sushi or sashimi in cucumber cups or avocado halves.
Due to its smaller size, masago has a clumpy texture, despite its similar hue to tobiko. (Image credit: Geoff Peters/Flickr.)
