Kumquat
The kumquat is a small, olive-sized citrus fruit native to southern China. Unlike most citrus, it is usually eaten whole, because its sweet, aromatic peel balances a tart interior. In drinks it is used whole, sliced, preserved in salt or sugar, or steeped. It flavors teas, cordials, cold remedies, soft drinks and fruit liqueurs.
How kumquat is prepared
Kumquats are steeped whole or sliced in hot water with honey or sugar, and preserved salted kumquats are dissolved in warm water. The fruit is added to hot and iced teas, and cooked into syrups and cordials for soft drinks. It is muddled into mixed drinks and zero-proof cocktails, and macerated in spirits to make sweet liqueurs. Kumquat hybrids such as calamansi and limequat are used in similar ways, most notably in lemonade-style juices.

Origins: the golden orange of southern China
The kumquat is native to southern China, and Chinese writing mentions it from at least the 12th century. Its English name comes from the Cantonese words for 'golden orange.' Most citrus fruits are valued for their juice, but the kumquat is prized for its whole body: a thin, sweet, perfumed skin wrapped around sharply acidic flesh. That quirk shaped its role in drinks from the start. The fruit is usually steeped, preserved or infused whole rather than squeezed, so the aromatic oils of the peel carry through into the finished liquid.[1]
Salted and honeyed kumquat drinks in southern Chinese tradition
In Cantonese and other southern Chinese households, kumquats have long been preserved for drinking as well as eating. One familiar method packs the fruit in salt and leaves it to cure for months, often for years. A spoonful of the softened fruit and its brine is then mashed into hot water to make a salty, tangy tonic. It is traditionally offered for sore throats, hoarseness and coughs. Kumquats simmered or steeped with honey or rock sugar make a sweeter warm drink for the same purpose. The fruit's golden color also made it a symbol of wealth. Potted kumquat trees decorate homes at the Lunar New Year, linking the everyday remedy with festive good fortune.[1]
East Asian cultivation and sweetened kumquat syrups
The kumquat has been grown for centuries beyond China, in Japan and across East Asia. The Meiwa kumquat, a thick-leaved type eaten skin and all, was brought from China to Japan at the end of the 19th century. In Japan, kumquats are commonly simmered in sugar syrup. The glossy candied fruit, and the syrup itself, are stirred into hot water as a soothing winter drink. In Taiwan and Hong Kong, kumquat juice paired with lemon or other citrus became a staple of tea shops and drink stands. It is served over ice or warm, often sweetened with honey or preserved plum.[2]
Kumquats in the tea glass of the Philippines
In the Philippines, oval kumquats are often dropped into hot or iced tea, adding both a sour accent and a fragrant peel. The same fruits are also eaten fresh, pickled, preserved in syrup or turned into jam. Macerated in vodka or another clear spirit, they make a simple homemade liqueur. The oval, or Nagami, type is the one most widely grown outside Asia. It is also sometimes grafted onto calamansi rootstock, a sign of how closely the two fruits are linked in regional growing and drinking.[3]
Calamansi: the kumquat hybrid behind a national drink
The most important drink connected to the kumquat comes from its hybrid, calamansi. This small, sour fruit is thought to be a cross between a kumquat and a mandarin, and it is grown mainly in the Philippines. Crushing the whole fruit yields a juice that is sweetened and diluted into a lemonade-like drink, now one of the country's everyday refreshments. The fruit also flavors teas and soft drinks. Frozen whole, it can serve as flavored ice. Calamansi juice is exported in large volumes. In Florida, where the fruit is known as calamondin, home growers use it for summer lemonades and limeades.[4]
Europe: from Victorian novelty to Mediterranean liqueur
The plant collector Robert Fortune brought the kumquat to Europe in 1846. The fruit was first grown mainly as an ornamental curiosity, prized because it tolerates cold better than most citrus. Its most lasting European drink tradition took hold on the Greek island of Corfu. There the fruit is steeped to make sweet, brightly colored kumquat liqueurs, which became a signature local product and souvenir. Similar home infusions, often made with sugar and a neutral spirit, appear wherever the tree is grown in Mediterranean gardens.[1]
The Americas: Florida groves and new hybrids
The Nagami kumquat reached Florida from Japan in 1885 and became the state's most commonly grown variety. Florida kumquats went mostly into preserves, candies and baked goods, but they were also muddled or sliced into punches and citrus drinks. In the early 20th century, American breeders crossed kumquats with other citrus to produce cold-hardy hybrids. One is the limequat, a cross with the Key lime made in 1909. It has a sweet skin and lime-like pulp, and it is used to flavor drinks and cocktails.[5]
Contemporary use in low- and no-alcohol drinks
Today kumquats appear in modern beverage menus well beyond their home regions. The peel's essential oil is mostly limonene, with smaller spicy and woody notes, which gives the fruit an aroma more complex than ordinary orange. This makes whole kumquats well suited to infusions. Bartenders and home makers muddle them into zero-proof cocktails and simmer them into syrups and shrubs. They also add them to sparkling water, iced tea and fermented tea drinks. Across Asia, the older traditions continue alongside these uses: the salted kumquat tonic, the honeyed winter drink and kumquat-lemon iced tea.[1]
