Native to China, the Yuzu has been used and cultivated in this region for thousands of years. The fruit is tart, resembling a grapefruit with mandarin overtones. It is rarely eaten as a fresh fruit, but is used to makes sauces, preserves and a popular yuzu vinegar. In Korea, thinly sliced fruits are combined with sugar and honey to make a thick marmalade like syrup. Yuzu kosho is a spicy Japanese sauce made from green or ripe yellow yuzu zest, chillis and salt. The yuzu is more cold tolerant than most other citrus, being able to tolerate to -5 degrees ❄
