Water Chestnuts (Singhada)

In India a man harvesting the beloved water chestnuts

Water chestnuts are often used in Chinese cooking.  The knobby vegetable with the papery brown skin is a staple in Chinese cooking. The water chestnut is actually not a nut at all, but an aquatic vegetable that grows in marshes. (This is why the ones that you purchase in the store may have a muddy coating.)

The name "water chestnut" comes from the fact that it resembles a chestnut in shape and coloring. Indigenous to Southeast Asia, it has been cultivated in China since ancient times.

Availibility: Water chestnuts require a long frost-free growing season (7 months) which means that they are only grown in semi-tropical areas, including a few States such as here in California and Florida. I can readily find fresh water chestnuts in most Asian markets year round.
Unless you live in an area where they are grown locally, they are generally not available in local groceries and supermarkets.
When choosing fresh water chestnuts, look for firm ones with an unwrinkled skin and no soft spots - otherwise when you peel the water chestnut you may find it has softened and turned mushy brown. Generally, it's best to buy a few more chestnuts than needed, just in case a few have spoiled.  Also avoid any chestnuts that look moldy as this taste will permeate the chestnut flesh.
Here is a photo of a boy harvesting water chestnuts after the monsoons.
Unpeeled, fresh water chestnuts will keep for up to two weeks in a plastic bag in the refrigerator. I prefer to buy them and cook in boiling water right away.
Prior to cooking, you'll need to cut off the top and peel the skin. If you want to peel them ahead of time, that's fine, but be sure to store them in cold water in the refrigerator, with the water changed daily.

Store canned water chestnuts in a cool dry place and use within a year. Once opened, store the water chestnuts in a sealed container in the refrigerator and use within three days.
Preparing Water Chestnuts: As mentioned above, fresh water chestnuts need to be peeled and the top cut off before using. Before using canned water chestnuts, rinse them under warm running water is said to remove any "tinny" taste, but I find them still starchy and tinny.  I much prefer to use only fresh water chestnuts.

When to Use Water Chestnuts
Water chestnuts are frequently added to stir-fries, stuffings, and dumpling fillings for extra texture and a sweet flavor.

Fresh or Canned?: Fresh water chestnuts are worth hunting for, as they have a sweeter flavor and are quite crisp. However, canned water chestnuts can be used as a substitute, particularly if they are being added mainly for texture. Definitely try to use fresh water chestnuts in appetizers such as Bacon Wrapped Water Chestnuts, or any other dish where the water chestnut is the main ingredient.

Indian Water Chestnut

Singhada, the Indian Water Chestnut is green and sometimes bright pink on the outside and white inside. It has a  crunchy and sweet taste.  It is sold by street hawkers either raw or steamed.  When steamed, the outside covering becomes  blackened and it tastes starchy, sort of like a potato.

Singhada is peeled, dried and crushed to get water chestnut flour called singhade ka atta which is used to prepare rotis and pooris.

Water Chestnut Flour is made from dried, ground water chestnuts. The nuts are boiled, peeled, dried then ground into flour.

The flour, which is actually a starch rather than a flour, is bright white fine powder.

It's primary use is as a thickener. It is also used in Asian recipes to make batters for deep-frying.

Water Chestnut Flour gives a light crust when used for dredging, and stays white as a coating even when fried.

It is very different from French or Italian chestnut flour, which is quite sweet and used for pastries.

Great blog Mary-Anne! Water chestnut flour aka Singhade ka atta is also widely used to make prasad for pujas. Many Indian folks do fruits-only fasting due to religious and dieting reasons. They do not eat any grains on specific days in a month. Singhade ka atta is a popular substitute for wheat flour on those days. It is used to make singhade ke atta ka halwa, which is enjoyed by all family members in the house.

Lalu Perhaps you are not aware that water chestnuts are grown in many many countries! I have never seen water chestnuts from India in the US, Europe, Australias, Southeast Asia, etc. I buy fresh locally (California) grown water-chestnuts and they are wonderful! They are a good source of potassium. A half-cup of water chestnuts contains around 350 to 360 mg of potassium. Also the water chestnuts I have seen growing Kerela seemed to be in fresh clean water.....butr things are different often times in Kerela than other parts of India I know. So you can grow your own waterchestnuts and be organic and have no worries! http://www.earthcare.com.au/wchestnuts.htm

Does anyone know where water chestnut flour can be purchased?

Most Asian markets carry it. It should be located near rice flour.

I just wanted to let you know that you are talking about two different species here that are both called water chestnuts. The Indian water chestnut is not the same as the Asian species. The Chinese water chestnut (Eleocharis dulcis), is eaten for its crisp corm, and is safe to eat peeled and raw. The Water caltrop (Trapa natans), eaten for its starchy seed, is not safe to eat raw, as it contains a toxin.
