Yuzu Juice in gelato
Yuzu juice is the intensely sour, highly aromatic juice of Citrus junos, a Japanese citrus. In gelato it acts as a low-dosage flavor and acidity source rather than a sweetener or body-builder, since it is almost entirely water with very little sugar.

Open the balancerHow to use it in gelato
Use yuzu juice as an intense sour-citrus flavoring, not as a sweetening or anti-freezing agent. With only ~1.8 g sugar per 100 g, its POD (~2) and PAC (~3) contributions are negligible, so it barely shifts serving temperature or sweetness even at working dosages. Its high organic-acid load (citric + malic ~4%, pH ~2.4) sharpens flavor and can react with dairy proteins, so balance it against milk/cream or pair with a neutral sorbet base. Recalculate sugars and PAC from the rest of the recipe to hit target hardness; treat yuzu almost purely as aromatic acidity.
Origin & background
Yuzu (Citrus junos) originated as a hybrid in East Asia and has been cultivated in Japan and Korea for centuries, where it is prized in cuisine and winter bathing rituals. An HPLC survey of 41 commercial juices from across Japan found citric acid ranging 2.97 to 4.75% and a mean total sugar of only 1.76%, confirming its characteristically tart, low-sugar profile.
