Lemon grass is an essential ingredient in Thai and Vietnamese cuisine and is sometimes found in Caribbean recipes. A tropical, stalky, grass plant that is considered an herb, lemon grass provides a distinctive zesty lemon flavor and aroma. It is available in ethnic markets in a variety of forms, including fresh, freeze-dried, or powdered. The white base has a bulb similar in appearance to a green onion but more the size of a leek. The long green stalk is very fibrous, coarse, and hard. The entire stalk of the grass can be used to flavor tea, sauces, soups, and curry dishes. The grass blade can be sliced very finely and added to soups. The bulb can be bruised and minced for use in a variety of recipes. The light lemon flavor blends well with garlic, chilies, coriander, and cilantro.
