What Is Ikura (Salmon Roe) and How Is It Used?

What Is Ikura (Salmon Roe)?

Ikura is a fish egg of salmon and trout.
In English, it’s usually expressed as salmon roe, salmon caviar, or red caviar.

In order to take ikura from salmon or trout, you need to remove a thin film of the ovaries that wraps the egg, and divide the ripe eggs before spawning into individual eggs.
Generally, it is not heat-processed and is eaten after being marinated in salt or soy sauce.

When you think of the size of ikura based on salmon roe, trout roe is slightly smaller and more reasonable than salmon roe.

By the way, the term “ikura” is come from Russian. But, I’ve heard that “ikura” in Russian means the whole fish eggs (including fish other than salmon and trout) unlike the meaning of “ikura” in Japanese.
It is said that the custom of eating salmon roe was also transmitted from Russia. However, it seems that Russia does not eat salmon roe on a daily basis as much as in Japan.

What Does Ikura (Salmon Roe) Taste Like?

The egg membrane cracks and the inside of the egg pops out at the moment you chew ikura. It feels a little oily.

You may feel richness of the ikura, but the taste is actually light and simple. So, it will be much more delicious if it’s marinated in soy sauce-based sauce. The marinate sauce takes away the bad smell of ikura, and you can directly feel the umami of them!

Are you interested in the differences between the taste of salmon roe and trout roe?
Sometimes people say trout roe has more rich and strong sweetness than salmon roe. However, it is thought that this is largely due to individual differences in the fish itself and the seasoning of salt, soy sauce, etc. during processing rather than the differences between salmon and trout.
