You do yuzu.
Yuzu is an exotic fruit that offers a hint of delightful tartness to the Yuzu Lemon Caffeine Infusion Pod and your yuzu water. The pod also contains 89 milligrams of caffeine from green coffee bean extract, just enough to perk the mind.
The yuzu fruit has its origins in central China and Tibet where it grows in the wild and is also cultivated. Yuzu grows on vertical shrubs or small trees with thorns. The fruit grows slowly, requiring 10 years to mature. The fruit itself can be yellow or green in color depending on its level of ripeness. They range in size, with a diameter of two to three inches, however they can grow as large as grapefruits. The skin of the yuzu fruit is uneven in texture. The fruit and its leaves possess a strong fragrance.
In Japan, an ornamental version of yuzu called hana yuzu or "flower yuzu" is grown for its flowers rather than its fruit.
