Does the taste of wasabi differ depending on the grater?!

Sushi restaurants use two types of tools for grating wasabi. One is a metal grater, and the other is called “samegawa” (shark skin), which consists of shark skin attached to a wooden base.

Using a material as fine as shark skin allows the aroma to first escape through the nasal passages, resulting in a taste that is initially sweet and gradually becomes spicier. This process breaks down the wasabi cells, creating a grated wasabi with high viscosity and rich flavor.

 

On the other hand, the metal grater has a coarser surface compared to the shark skin grater, resulting in grated wasabi with lower viscosity and a grainy texture. However, the shape of the surface protrusions varies, so this is merely a general rule.

Additionally, copper graters used by sushi chefs have antibacterial properties, making them safe for handling ingredients. Using a copper grater allows you to grate wasabi without crushing the fibers, resulting in a light and fluffy texture.

Finally, an interesting point is that the taste of the wasabi even changes depending on whether it is turned clockwise or counter-clockwise while grating. Of course, this depends on the orientation of the protrusions on the grater surface and is not related to the type of grater.

Strong belief that fish is only about freshness

In some cases, the strong belief that fish is only about freshness, may prevent you from tasting the true value of the fish. For example, slicing up a fish that was just swimming, in front of the customer. The umami flavor is weak at first so while the texture is tough (a unique, crunchy feeling), the flavor is lacking. But the idea that freshness is equivalent to deliciousness continues still. This is a typical case of faith in freshness overtaking the actual taste.

What is the difference between the taste of marbled and lined fatty tuna?

It is often said that when you eat Otoro, it melts in your mouth like a snowflake. With its smooth texture and rich flavor, it is enormously popular. Otoro is located on the belly side near the head and can be divided into two types.

Marbled tuna (Shimofuri) is the part in which it looks like the fat has fallen like a frost and melts like snow on your tongue then leaving only the umami taste. By cutting thinly and widely at an angle to the saku, a delicate flavor and aroma are produced.

The lined fatty tuna (Jabara) is the part that has white fat lines running through it. When you first take a bite, surge of aroma and umami flavor fills your mouth. After that, the potent fatty umami fills your mouth. Cut the Jabara into thick, slightly shorter pieces and make nigiri sushi.

The way the fat melts in your mouth differs between Jabara and Shimofuri, so which you like better depends on preference.

Some people find the fat in Otoro to be too rich. By searing it, the excess fat is removed and the moisture is evaporated, so the umami components are concentrated, and adding a savory aroma enhances the flavor.
