Versatility of an Herb

If forced to choose just one seasoning ingredient, it would be cilantro. As long as I have this herb in the kitchen or a cilantro plant in the garden, I don't even need pepper, which is my second favorite seasoning. It is popularly known as an ingredient in Mexican dishes, but its use has spread to several others. In addition, I like to sprinkle it on any type of salad, from fresh spring greens to potato salad.

Cilantro is sometimes called Chinese parsley, but it originates with the coriander plant or the Latin Coriander sativum. The seeds of the coriander plant are ground to make powdered coriander, while the leaves of the plant become the herb cilantro. In addition to seeds and leaves, all parts of the coriander plant are edible.

Unique Flavors Of Cilantro

Coriander is an annual herb plant, meaning that it needs to be replanted each year.

A member of the plant family Apiaceae, the herb originated in the Middle East, southern Europe, North Africa, and parts of Asia. In those areas, the herb is popular in cuisine and medicine, but it is also used often in Mexican dishes.

The plant coriander grows to a height of nearly two feet, with leaves that resemble flat-leaf parsley and are rather feathery, and finer than parsley. In fact, some cook confuse curly parsley, flat-leaf parsley, and cilantro, especially the last two.

In most of the world, cilantro is known as coriander, but Americans call it cilantro. The world culantro is Spanish for the coriander plant, but some herb growers feel that cilantro (coriander) and culantro are two different plant varieties with distinct flavors. Look for them at farmers markets and specialty stores and try them both.

The flavor of the leaves deteriorates very rapidly after picking and the leaves are usually not cooked, because that leeches all the flavor from the cilantro. Cilantro is primarily used raw and whole-leafed, or chopped in recipes or as a garnish. It is flavorful in salsas, chutney, some curries, salads, and even with some fruits. Cilantro lime rice is a favorite dish of many and is often served in America's Mexican restaurants.

While its flavor is best in the raw state, cilantro is found to contain antioxidants that prevent the spoiling of foods that contain it. In other words, the flavor of cilantro may fade, but the total food dish stays fresher longer.

Store small amounts of fresh coriander leaves in the refrigerator after, making sure they are dry, in a container that will keep them dry and preferably in a refrigerator drawer away from light. Dried, crushed cilantro leaves are available as well, but are best purchased only small packets, as the dried leaves lose flavor quickly. Fresh cilantro should be used within 2-3 days or picked, as needed, from a garden plant.

Coriander Seeds

Coriander seeds can be used in a variety of cooked dishes and comes powdered, in shaker bottles in the grocery baking aisle where spices are displayed. Whole seeds are also available and will retain their flavor longer than the powdered style (grind as needed). Keep either in an opaque container away form sunlight that can leech flavor.

In Indian cuisine, coriander is popular in curries and garam masala and is often used in tamden with the smokier cumin. Seeds can be toasted as a snack or boiled for a medicinal tea that fights respiratory problems.

Coriander seed is also found in small boxes of "pickling spices" in the grocery store. These spcies are used for pickling fruits and vegetables and in sausage making. The seeds can be combined in a number of combination with additional spices found in curry powders as well.

Coriander roots can also be used in cooking, presenting a deeper, darker flavor than the seeds.

Don't like the taste if it, but its excellent for detoxing heavy metals.

Audrey Kirchner from Washington on July 02, 2010:

One of my favorite herbs. I am trying to grow it this year although it does not seem to flourish as well in Central Oregon (nor does basil) but I'm going to get them their temps yet!

Thanks for the comments!

@soni2006 - The chutney combinatin of ingredients youdescribes sounds very tasty to me. I don't the incidence rate of cilantro allergy but I had an allergic reactionn to it only once. It was home-grown from a friend's garden and so, it may have come in contact with insecticides of gardens next to it, even though I washed and dried the cilantro. Just something to be aware of in the use of herbs - allergies and contact with chemicals.

Rajinder Soni from New Delhi, India on June 05, 2010:

Cilantro in Hindi is called as hara dhaniya and is commonly called coriander in Engish. I used to ate raw cilantro once every week when I was a teenager. It is added in most of the recipes here in India. Cilantro is the most important ingredient in making spicy dhania chutney, other ingredients include salt, pepper, raw mango, little bit of lemon juice and it can be made in a grinder. The most important thing is that many of my friends and relatives consume cilantro on a frequent basis and have not had a single allergy or complaint with this super herb.
