What Is Yuzu and What Does It Taste Like?

Yuzu is on half the dessert menus and cocktail lists in Singapore, and it is on ours three times. Yet most people who order it could not pick the fruit out of a bowl of citrus, and the usual description — “a Japanese lemon” — is wrong in almost every way that matters. Here is what yuzu actually is, what it tastes like, and why a fruit that gives so little juice is worth what it costs.

What yuzu is

Yuzu is a citrus fruit, botanically Citrus × junos. The × is the important part: it is a hybrid, and the usual account is that it arose in central China as a cross between a type of mandarin orange and the Ichang papeda, a hardy, sour, rather wild citrus. It reached Japan from China a very long time ago — Nippon.com dates its introduction to the Nara period, which ran from 710 to 794 — and Japan is where it became a staple.

That papeda parent explains one of yuzu’s oddest traits. It is unusually cold-hardy for a citrus, able to survive winters down to around −7°C, which is why it can be grown across much of Japan where lemons would struggle. It is also slow: the tree grows gradually and generally takes around ten years to fruit.

What it looks like

Roughly palm-sized. Japan’s trade body, JETRO, puts a typical fruit at about 120–130g, and most are 5.5 to 7.5cm across, though some grow as big as a grapefruit. The skin is thick and lumpy rather than smooth, and the colour depends on when it is picked: green early in the season, yellow when ripe. Cut one open and there is surprisingly little flesh and a great many seeds. If you are expecting a lemon’s worth of juice you will be disappointed.

What yuzu tastes like

This is the question most people are really asking. Yuzu is sour, but its sourness is not the point. The point is aroma: floral, sharp and bright, usually described as sitting somewhere between grapefruit and mandarin, with a faint bitterness at the edge. A lemon is mostly acid with a clean citrus smell; yuzu smells more complicated than it tastes.

Most of that aroma lives in the rind rather than the juice, which is why Japanese cooks use the zest as often as the juice, and why a bottle of pure yuzu juice never quite tastes like the fruit smells. It is also why yuzu works so well in small amounts: a little lifts a sauce, a lot flattens it.

Green yuzu and yellow yuzu

The two colours are the same fruit at different moments, and Japan uses them differently. JETRO describes aoyuzu, green yuzu, as shipped between summer and autumn, and kiyuzu, yellow yuzu, from autumn onwards, noting that the yellow fruit is juicier. Shipments of the fresh fruit are concentrated between November and January. Green yuzu is prized for its sharp, green zest; yellow for its juice and fuller perfume.

Where it comes from, and why it is expensive

Japan produces roughly 27,000 tonnes of yuzu a year, and about half of it comes from one prefecture. JETRO gives Kōchi, on the island of Shikoku, about 52% of national production, with neighbouring Tokushima and Ehime next at 13% and 11%. Between them the three Shikoku prefectures grow most of the country’s crop.

Put the numbers together and the price makes sense. It is a slow tree, grown mostly in one region, that gives a small, seedy fruit with little juice, and the part people want most — the aroma — is concentrated in the rind, which does not travel as well as juice. Outside Japan, fresh yuzu is scarce and dear, which is why most of the yuzu you meet in Singapore arrives as bottled juice, zest, paste or syrup rather than as whole fruit.

How Japan uses it

Ponzu. Yuzu is one of the classic citrus choices for ponzu, the sharp citrus-and-dashi sauce; commercial yuzu ponzu was developed in Kōchi in the 1960s.
Yuzu kosho. A fiery paste of yuzu zest, chilli and salt, green or red depending on the zest and chillies used. It is the seasoning that turns up on grilled chicken at a yakitori counter.
Zest on almost anything. A strip of rind floated in a clear soup or grated over a simmered dish is a very old Japanese move.
Tea and sweets. Yuzu is candied, turned into marmalade-like preserves for tea, and used in desserts.
The bath. On tōji, the winter solstice, whole yuzu are floated in the bath, a custom that dates back at least to the Edo period. Nobody eats those.

Where yuzu turns up on our menu

We use yuzu in three places, and in all three it is doing a job rather than decorating.

The garlic-yuzu toum served with the Lebanese charcoal chicken. Toum is a Lebanese garlic emulsion that normally gets its sourness from lemon; we use yuzu instead. Our toum post explains why that is a substitution rather than an addition, and our piece on how the two cuisines fit makes the same point about the whole menu: both traditions have an acid slot, and yuzu can fill the Levantine one without displacing anything.

The yuzu beurre blanc on the Atlantic seabass. A beurre blanc is a butter sauce that needs acid to hold its shape and cut its richness; yuzu brings the acid and the perfume in one. The seabass post goes into what that does to the plate.

S.S.S., one of the signature cocktails: yuzu, tequila, dry curaçao and a seaweed salt rim. Tequila and citrus is a familiar pairing; swapping lime for yuzu makes it smell of something else entirely. It is written up in our S.S.S. cocktail spotlight.

How to use yuzu at home

If you have bought a bottle of yuzu juice, a few honest rules:

Use less than you think. Start with half the amount of lemon a recipe calls for and taste. Too much turns bitter.
Add it late. The aroma is volatile. Heat drives it off, so dress, finish or stir it in off the heat.
Put it near fat. Yuzu is at its best cutting something rich: butter, mayonnaise, grilled fatty fish, pork, avocado.
Check the label. Many “yuzu” products are mostly other citrus, sugar or flavouring. If the smell is faint, the yuzu probably is too.

Tasting it properly

The simplest way to understand yuzu is to taste it next to something it replaced. Order the charcoal chicken and try the toum on its own before you use it; that is a Lebanese sauce with a Japanese citrus in it, and the difference from a lemon toum is exactly the difference this post has been describing.
