Kumquat

Kumquat is sour and is often used for preserves or cooking. It is used to flavor foods and drinks. Despite its outer appearance and its aroma, the taste of the fruit itself is quite sour, although the peel is sweet. The fruit is a source of vitamin C.

The fruit can be frozen whole and used as ice cubes in beverages such as tea, soft drinks, water, and cocktails. The juice can be used in place of that of the common Persian lime (also called Bearss lime). The juice is extracted by crushing the whole fruit, and makes a flavorful drink similar to lemonade. A liqueur can be made from the whole fruits, in combination with vodka and sugar.
