This is a very pungent herb and is normally used in small amounts. The entire stalk of the grass can be used. The grass blade can be sliced very fine and added to soups. The bulb can be bruised and minced for use in a variety of recipes. (See recipes at the bottom of this page).
The light lemon flavor of this grass blends well with garlic, chilies, and cilantro. The herb is frequently used in curries as well as in seafood soups. It is also used to make tea.
Lemon grass is available in ethnic markets such as Asian and Mexican. Select fresh looking stalks that don't look dry or brittle. Store fresh lemon grass in the refrigerator in a tightly sealed plastic bag for up to 3 weeks. You can also freeze it for about 6 months without any flavor loss.
In addition to fresh, lemon grass may be purchased dried or powdered. The dried product has to be soaked in hot water and reconstituted before use. The powdered variety is useful in teas and curries but it's not a good substitute for the fresh product. For best results in recipes use the fresh herb.
This grass is rich in a substance called citral, the active ingredient in lemon peel. This substance is said to aid in digestion as well as relieve spasms, muscle cramps, rheumatism and headaches.
