Yuzu (Japanese Citrus): what every chef needs to know
Yuzu (Japanese Citrus) — a Japanese citrus variety with a unique aromatic profile: a combination of lemon, grapefruit and mandarin with floral, honey-like undertones. The juice is intensely sour (pH 2.8) but is used sparingly — a single tablespoon of yuzu juice can transform an entire dish. The zest is the most aromatic component and can be used wherever lemon zest is called for. Commercial yuzu juice and zest are available in three forms: fresh, frozen juice and yuzu-kosho (a paste of green yuzu zest and green chilli). For commercial kitchens outside Japan, frozen yuzu juice is the most practical option and is comparable in quality to fresh juice for sauces and dressings. Yuzu contains three times more vitamin C than lemon and a unique combination of terpenes (linalool, limonene and yuzu-specific compounds) found in no other citrus fruit. Yuzu trees are extremely slow-growing — a seedling takes 18–20 years to bear fruit for the first time. This makes yuzu trees a precious heirloom in Japan.

Frequently asked questions about Yuzu (Japanese Citrus)
What is a good substitute for yuzu juice?
No single fruit exactly replicates yuzu's profile. The best approximation: 2 parts lemon juice + 1 part grapefruit juice + 1 part mandarin juice. Alternatively, lemon juice with a few drops of bergamot oil (dose carefully — very potent). Frozen authentic yuzu juice is the most recommended professional solution.
What is the difference between yuzu and yuzu kosho?
Yuzu is the fruit (juice, zest). Yuzu kosho is a fermented paste of green yuzu zest, green chilli and salt. They are completely different in application: yuzu for bright citrus acidity, yuzu kosho for spicy-citrus punch.
Can I use both the juice and zest of yuzu?
Yes — both are valuable. Juice for ponzu, dressings and cocktails. Zest as an aroma burst on hot dishes just before serving. Getting full use from a whole yuzu is the professional standard: nothing goes to waste.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
