Yuzu
Yuzu is a citrus fruit and plant in the family Rutaceae of East Asian origin. It is usually available in winter. It is very rare and is only produced 27000 tons a year, mostly produced at Kochi prefecture. This fruit's color varies depending on how ripe it is, but it resembles a little grapefruit with uneven skin and a yellow or green hue. Although they can be as huge as a standard grapefruit, yuzu fruits typically have a diameter between 5.5 and 7.5 cm and are incredibly scented.
Yuzu forms an upright shrub or small tree, which commonly has many large thorns. Leaves are notable for a large, leaf-like petiole, resembling those of the related kaffir lime and ichang papeda, and are heavily scented. Many characteristics of yuzu are similar to those of sudachi, but unlike sudachi, yuzu finally ripens to an orange color and the flavors of the fruit change just slightly from one another.
