The tamarind tree (Tamarindus indica) is a leguminous tree bearing edible fruit that is probably indigenous to tropical Africa. Of all the fruit trees of the tropics, none is more widely distributed nor more appreciated as an ornamental than the tamarind tree.
Tamarind tree fruit
The fruit is harvested by pulling the pod from its stalk. The fruit has a fleshy, juicy, acidic pulp. It is mature when the flesh is colored brown or reddish brown. The tamarinds of Asia have longer pods (containing six to 12 seeds), whereas African and West Indian varieties have shorter pods (containing one to six seeds).
This tree seedling is an Asian variety. The fruit is best described as sweet and sour in taste, and is high in tartaric acid, sugar, B vitamins, and, unusually for a fruit, calcium.
As the tamarind tree fruit matures it becomes sweeter and less sour (acidic) and the ripened fruit is considered more palatable.
The sourness varies between cultivars and some sweet tamarind ones have almost no acidity when ripe. This tamarind tree seedling is a sweet variety.
In Western cuisine, tamarind pulp is found in Worcestershire Sauce and HP Sauce. Tamarind paste has many culinary uses including a flavoring for chutneys, curries, and a traditional sharbat syrup drink. Tamarind sweet chutney is popular in India and Pakistan as a dressing for many snacks and often served with samosa.
Tamarind pulp is a key ingredient in flavoring curries and rice in south Indian cuisine, in the Chigali lollipop, in rasam, and in certain varieties of masala chai tea.
Across the Middle East, from the Levant to Iran, tamarind is used in savory dishes, notably meat-based stews, and often combined with dried fruits to achieve a sweet-sour tang.
In the Philippines, the whole fruit is used as an ingredient in the traditional dish called sinigang to add a unique sour taste, unlike that of dishes that use vinegar instead. Indonesia also has a similarly sour, tamarind-based soup dish called sayur asem. In Mexico and the Caribbean, the pulp from the fruit of the tamarind tree is diluted with water and sugared to make an agua fresca drink. It is widely used throughout all of México for candy making, including tamarind mixed with chilli powder candy.
