SPICE DICTIONARY: SERAI (Cymbopogon/Lemon Grass)

Lemon grass is widely used as an herb in Asian cuisine. It has a citrus flavour and can be dried and powdered, or used fresh.

Lemon grass is commonly used in teas, soups, and curries. It is also suitable for poultry, fish, and seafood. It is often used as a tea in African and Latino-American countries (e.g., Togo, Mexico, DR Congo).

East-Indian Lemon Grass (Cymbopogon flexuosus), also called Cochin Grass or Malabar Grass, is native to Cambodia, India, Sri Lanka, Burma,and Thailand while the West-Indian lemon grass (Cymbopogon citratus), also known as serai in Malay, is assumed to have its origins in Malaysia. While both can be used interchangeably, C. citratus is more suited for cooking. In India C. citratus is used both as a medical herb and in perfumes.
