There are a handful of people who love sushi all over the world. Perhaps you haven’t tried some yet, and you want to, you can take this as a sign.
If you are yet to try more sushi out there, you may have encountered fish eggs and wondered, “What are fish eggs on sushi?”
Fish Eggs on Sushi
While eating sushi, you must have encountered the small round ingredients usually coating the outside of the slice. These fish eggs are also called roe.
This term refers to fish eggs used in a dish or included in various garnishes. There are three common types of fish roe used in sushi, namely Tobiko, Masago, and Ikura. Let’s talk about the first type; introducing tobiko.
Tobiko is roe laid by flying fish species. The term ‘tobiko’ came from shortening the phrase ‘tobiuo no ko,’ which directly translates to ‘flying fish roe .’Flying fishes lives in the open ocean and primarily eat zooplankton.
These fishes are typically located in tropical and sub-tropical areas. You probably heard or seen them on television as they can fly! These fishes have evolved and developed the capacity to glide to escape threats and dangerous situations.
They are perhaps at the top of the list for popularity, as many people worldwide know about them. These tiny eggs can range from 0.5 to 0.8 mm, and bigger ones can be 0.9 mm or more, but the typical sizes do not exceed 1 mm.
Tobiko has an exciting pop to it when eaten. They have a mildly salty, smoky, and briny taste. Tobiko is also relatively sweeter than other types of fish eggs.
When placed in dishes, these eggs are easily spotted because of their vibrant color of bright red and orange. On the other hand, different cooks add extra things to their fish roe to spice its flavor.
As for color alterations, chefs usually infuse tobiko with the following natural ingredients.
- Squid ink to make the color darker or blacken tobiko.
- Yuzu to alter the colors into yellow.
- Wasabi helps make tobiko greenish.
- Beet to transform it to a redder shade or a particular red shade desired.
The next type of fish roe is called Masago. Masago means ‘sand’ and is termed that way because of its appearance.
These eggs are from a forage fish called capelin coming from the smelt family. In fact, eggs from any member of the smelt family are called Masago.
While these eggs are usually mistaken as Tobiko, especially those unfamiliar with fish roe, Masago’s color is less bright. They come in a red, orange, and red-orange shade but are paler than Tobiko.
Tobiko and Masago are also differentiated through their size as Masago is smaller than Tobiko, and so is the sensation when you consume them.
While tobiko provides a satisfying crunch when you bite onto them, Masago does not have any crunch to them. They are somewhat sandy than crunchy. These eggs are also slightly bitter.
Despite these differences, Masago is often used as a substitute for Tobiko. They are often dyed to create a more vibrant and brighter color mimicking Tobiko.
Tobiko is expensive, so using Masago as an alternative can be an ideal option for some people, given a different situation or perhaps a shortage in stock.
Ikura and Caviars
Ikura is the Japanese term for Salmon roe. These eggs come from salmon and are noticeably larger than Tobiko and Masago and other common fish roe. Ikura also has a distinctive color because of the difference in its intensity.
In terms of appearance, these eggs have a way more intense red-orange color with quite a transparent and shiny egg appearance. In addition, they should have a good smell and rich and bold flavor.
With a gooey texture, Ikura is quite more delicate, so it should be handled carefully for the eggs not to pop or get punctured.
In the past, Ikura was formerly curated in salt, but the more modern and common marinate for these eggs is soy sauce; it could be with extra spice or just plain. This fish roe is often enjoyed wrapped with a crunchy seaweed sheet.
This is also called Cajun caviar and has a local name of ‘choupique’.
These eggs come from bowfins, and despite not being a part of the sturgeon family, its eggs are known to be of high quality while also being in the affordable department. Bowfin caviar is a good sushi garnish.
Black Lumpish caviar
These eggs are one of the inexpensive entry-level caviar available on the market. They are ideal when you are new to the caviar world and good caviar for gourmet meal recipes.
These eggs are crunchy and have a salty fish flavor to complement other ingredients.
These eggs come from the European rainbow trout and are bright orange. They have a smokey and sweet flavor that is compatible with many dishes.
These golden yellow eggs come from the Great Lakes of North America. They have a mild taste and go very well with many dishes like soups, sushi, etc. Whitefish caviar can also be featured in different sauces.
