Lemon grass is exactly what the name suggests- a grass that smells of lemons. It is a native of the tropics and is said to originate in India and South East Asia. The tough stringy stalks are used in Thai and Vietnamese food.

Lemon grass is actually the name given to several grasses which contain essential oils with citral. This gives them their unique lemon scent which is most noticeable in the fresh leaves and stems.

Lemon grass is long, fibrous and coarse in texture. It has a bulbous portion at the root end, the insides of which are softer than the outside. It is this portion that is most often employed as a flavouring in food. This bulb-like portion can be sliced, minced, ground or pounded and added to food. The dried powder is called “Sereh powder”.

As with most herbs, fresh lemon grass is preferred to the dried stalks though this is also used. In their dried form the stalks are available cut or sliced, as a powder or as an essential oil.



Store lemon grass stems in a paper bag in the refrigerator. They can last upto 2 to 3 weeks like this. The grass can also be frozen, and will keep for upto three months but frozen lemon grass does not have such an intense aromatic flavour. The leaves should be stored in airtight containers separately from the stalks and also from other food that tends to absorb this strong aroma.

Culinary Uses

Lemon grass is inseparable from Thai, Malasian and Indonesian food and is also used in Sri Lankan and Indian cooking. Most often used in dishes like curries,(meat, poultry, seafood and vegetables) where coconut milk is used. It's lemon flavour provides balance to the unctuousness of that extract.

Lemon Grass stalks are also infused into teas, pickles and marinades.Sereh Powder is used along with other herbs and spices as a rub for grilled meats.

To use sereh-powder as a substitute, one teaspoon of the powder may be substituted for one stem of the fresh grass. If dried lemon grass is used, it must be soaked for two hours in tepid water before using in food.

An elegant and fragrant substitute for a satay stick is a stick of lemon grass which may be used to spear pieces of meat, poultry, seafood or vegetables before they are grilled.
