What Is Nikiri? Why Sushi Chefs Brush Sauce on Nigiri

It happens so quickly you can easily miss it. The chef finishes shaping a piece of nigiri, picks up a small brush and paints a thin glaze across the fish before setting it down. That glaze is usually nikiri, and it is one of the main reasons you rarely need to reach for the soy sauce at an omakase counter.

What is nikiri?

Nikiri is a light, glossy sushi sauce made by gently simmering soy sauce with mirin and often a little sake, sometimes with dashi added. The cooking takes the sharp edge off the soy and leaves it slightly sweet, mellow and rounded.

Every counter has its own version, and many chefs make it in house. It is a signature of the traditional Tokyo style, where each piece leaves the chef's hands fully seasoned; our guide to Edomae sushi for the first-time guest explains more.

Nikiri vs nitsume (tsume)

Not every brush carries the same sauce. You may see two:

• Nikiri is thin and soy-based, and suits most fish, from lean tuna to white fish.
• Nitsume, also called tsume, is thick, dark and sweet. It is made by reducing the cooking liquid of simmered fish, traditionally conger eel (anago), with soy, sugar and mirin until it becomes almost syrupy. It is brushed on anago and sometimes on simmered clams or other cooked toppings.

Why not just use soy sauce?

When you dip sushi into a dish of soy yourself, it is almost impossible to control how much you take. The rice soaks up too much, the piece falls apart, and soy floods the flavour of the fish.

A brush lets the chef apply a precise, even layer that sits on the surface of the fish. You taste the fish first and the seasoning second, which is the order the chef intends.

Different fish, different seasoning

Watch closely and you will notice the brush doesn't touch every piece the same way. A rich, fatty cut might take a full stroke; a delicate white fish might get the lightest touch, or none at all. Some pieces arrive with salt and citrus instead, some with a pinch of grated ginger or a little freshly grated wasabi.

That is the heart of omakase. The chef isn't only preparing the food; they are deciding how each piece should taste when it reaches you.

Should you add more soy sauce?

If a piece has been brushed, try it as served first. That first bite tells you exactly what the chef intended, and most of the time it needs nothing more. Adding soy on top of nikiri usually overpowers the balance.

If a piece arrives unseasoned and you would like soy, touch it lightly with the fish side down, never the rice. Chopsticks or fingers are both fine; eating nigiri with your hands is not rude.

Frequently asked questions

What is nikiri made of?

Nikiri is soy sauce gently simmered with mirin and often sake, sometimes with dashi. The result is a mellow, slightly sweet glaze for brushing onto nigiri.

What is the difference between nikiri and nitsume?

Nikiri is a thin, soy-based glaze used on most fish. Nitsume (tsume) is a thick, sweet reduction, traditionally made from the simmering liquid of conger eel, and brushed on anago and other cooked toppings.

Is it rude to add soy sauce to sushi that has been brushed?

It isn't rude, but it is unnecessary. The chef has already seasoned the piece, so taste it as served first.

Look for the brush next time

Omakase is full of small gestures that are easy to miss. Once you know what the brush is doing, it becomes one more part of the meal to watch. It isn't decoration; it is the final seasoning.
