lemon grass

Lemongrass (Cymbopogon citratus) is a tropical perennial grass native to India and Southeast Asia, characterized by long, slender, blade-like leaves that grow in dense clumps. The plant produces a pale, swollen base—the culinary portion—that resembles a miniature leek and is the primary part used in cooking. The entire plant, but especially the lower stalks and bulbous base, contains volatile oils rich in citral, which impart a distinctive lemony, slightly floral, and herbaceous flavor without any actual acidity. Lemongrass is grown extensively throughout tropical and subtropical regions, particularly in Thailand, Vietnam, and Indonesia, where it is a foundational ingredient in traditional cuisines.

Lemongrass is essential to Southeast Asian cooking, particularly in Thai, Vietnamese, and Indonesian cuisine. It is primarily used to infuse broths, curries, and soups with its aromatic citrus character—the outer layers are typically bruised and left in dishes to release their oils, then removed before serving, while the tender white interior can be finely minced for inclusion in pastes, marinades, and stir-fries. The herb pairs exceptionally well with coconut milk, lime, fish sauce, and chiles, and is a key component in many Southeast Asian pastes and curry bases. Beyond Asia, lemongrass is increasingly used in contemporary cooking for teas, infusions, and as a garnish in modern cuisine.
