Calamansi (Citrus × microcarpa), also known as calamondin, Philippine lime, or Philippine lemon, is an economically important citrus hybrid predominantly cultivated in the Philippines. It is native to the Philippines, Borneo, Sumatra, and Sulawesi in Indonesia in Southeast Asia, as well as southern China and Taiwan in East Asia. Calamansi is ubiquitous in traditional Filipino cuisine. It is naturally very sour, and is used in various condiments, beverages, dishes, marinades, and preserves. Calamansi is also used as an ingredient in Malaysian and Indonesian cuisines.
Uses
Calamansi is used in its partly ripe stage with soy sauce, vinegar, and/or labuyo chili as part of the most ubiquitous dipping sauce in Filipino cuisine.
The fruits are sour and are often used for preserves or cooking. The calamansi 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. Calamansi marmalade can be made in the same way as orange marmalade. Like other citrus fruits, the calamansi 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 with vodka and sugar.
Philippines
Calamansi juice from the Philippines
In Filipino cuisines, the juice is used to marinate and season fish, fowl and pork. It is also used as an ingredient in dishes like sinigang (a sour meat or seafood broth) and kinilaw (raw fish marinated in vinegar and/or citrus juices). It is very commonly used as a condiment in dishes like pancit or lugaw, or in the basic sawsawan (dip) of calamansi juice and soy sauce/fish sauce used for fish, spring rolls, dumplings and various savoury dishes. It is also used in various beverages, notably as calamansi juice, a Filipino drink similar to lemonade.
In other regions
Indonesia
The fruit is used in local recipes in northern Indonesia, especially around the North Sulawesi region. Fish are spritzed and marinated with the juice prior to cooking to eliminate the "fishy" smell. Kuah asam ("sour soup") is a regional clear fish broth made with calamansi juice.
Florida

In Florida, the fruit is used in its fully ripe form with a more mature flavor profile than the unripe version. Tasters note elements of apricot, tangerine, lemon, pineapple, and guava. The peel is so thin that each fruit must be hand snipped from the tree to avoid tearing. The entire fruit minus the stems and seeds can be used. It is hand processed and pureed or juiced and used in various products such as calamondin cake, coulis, marmalade, and jam. The peels can be dehydrated and used as a gourmet flavoring with salt and sugar. The fruit was popular with Florida cooks in cake form from the 1920s to the 1950s.
Floridians who have a calamansi in the yard often use the juice in a summer variation of lemonade or limeade, as mentioned above, and, left a bit sour, it cuts thirst with the distinctive flavor; also it can be used on fish and seafood, or wherever any other sour citrus would be used.
