The Calamondin bears a small citrus fruit that 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. Eating a whole fruit has a surprise with the combination of sweet and sour. Calamondin marmalade can be made in the same way as orange marmalade. Like other citrus fruits, the calamondin is high in 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 withvodka and sugar.
