To put it simply: Yuzu is delicious. A star of Japanese and Korean cuisine, the juice could be described as a cross between lemon, grapefruit and mandarin but that doesn't quite describe it. It's quite tart, like a lemon or grapefruit, but with the sweetness of mandarin. Yuzu juice can be used to make traditional ponzu (Japanese dipping sauce), mixed with oils and vinegars to create an incredible salad dressing, used in cocktails for a hit of brightness, or used in sorbets and desserts. The little citrus that could. 

This product is shelf stable due to the addition of vinegar as a preservative, but once opened it should be refrigerated.
