Yuzu
Citrus junos · Rutaceae · also known as Yuja, Japanese citron

How to select & store
Picking a ripe one
Choose heavy, deeply fragrant fruit with firm, bumpy yellow skin — the aroma should fill your hand. Green yuzu (autumn) is sharper and used for a distinct seasoning; yellow (winter) is rounder.
Storing it
Refrigerate up to two weeks; the zest and juice both freeze superbly (freeze juice in ice-cube trays, zest in a bag). A little goes a long way, so one fruit lasts many dishes.

Eating yuzu: what to know
What regular consumption looks like
Yuzu is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is exceptionally rich in vitamin C — even a small portion far exceeds a day's needs — supporting immune function, collagen formation, and the absorption of iron from plant foods. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Yuzu contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

Is yuzu good for you?
Yuzu is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is exceptionally rich in vitamin C — even a small portion far exceeds a day's needs — supporting immune function, collagen formation, and the absorption of iron from plant foods. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
How much yuzu should you eat?
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Yuzu is citrus used the way a perfumer uses a rare essence: never eaten out of hand — it is too sour, too seedy, too dry — but deployed drop by drop for an aroma that ranks among the most prized in world cooking. One knobbly fruit can perfume a whole meal.
Aroma over flesh
Where an orange is about juice, yuzu is about the oils in its bumpy rind — floral, sherbety, at once grapefruit, mandarin, and pine. Japanese cooks zest it over sashimi and simmered dishes; the juice sharpens ponzu. The flavor is so distinctive that “yuzu” now signals luxury on dessert menus from Tokyo to Paris.
A winter fruit with rituals
Cold-hardy yuzu ripens in winter, and both Japan and Korea built traditions around it: the Japanese solstice yuzu bath for warmth and good health, and Korean yujahcha, a honeyed yuzu-marmalade tea stirred into hot water against colds. Like calamansi in the Philippines, it is a small citrus with an outsized cultural footprint.
