Description
Sand ginger is a low-growing plant in the ginger family (Zingiberaceae) valued for its small, aromatic rhizome. Despite the name, it is a different species from ordinary ginger and from galangal — one of several rhizomes casually called "galangal" in older texts and markets.
The plant is stemless and close to the ground, with leaves that spread almost flat over the soil rather than rising on an upright shoot. The prized part is a compact, dark-brown, rounded rhizome with paler flesh, from which fine, aromatic roots spread. Its scent is warm and camphorous, and its flavour is peppery, slightly bitter and medicinal — quite unlike the citrus-pine heat of galangal or the bright spice of ginger.
In Indonesia, where it is called kencur, it is a cornerstone aroma — subtle enough to fold into fresh spice pastes, assertive enough to define a dressing or a drink. It is used far less in Thai cooking, where fingerroot (Boesenbergia rotunda) fills the more prominent aromatic role instead.
Origin & History
Sand ginger is native to tropical Asia, from India through Myanmar and Thailand to southern China, and has long been cultivated and carried further afield, reaching Sri Lanka, the Philippines and Sumatra. Its main culinary home is Java and Bali, where kencur seasons vegetable salads and rice dishes and is dried and milled into the rice-flour drink beras kencur. In China it is sold dried or ground as sha jiang and used in savoury cooking and traditional remedies.
Uses
Culinary
- Indonesian fresh pastes: Pounded with chilli, garlic and shrimp paste for pecel, urap and seblak
- Salad dressings: The key aromatic in the peanut-and-spice sauce for pecel and gado-gado beside galangal and turmeric
- Fried dishes: Grated or pounded into the seasoning of savoury rice crackers and fritters
- Drinks: Dried and ground, then mixed with rice flour and water to make beras kencur
- Chinese cooking: Dried sha jiang seasons steamed and salt-baked chicken and dipping sauces
- Leaves: The fragrant leaves are torn into the Malay rice-and-herb dish nasi ulam
Traditional Medicinal Uses
Sand ginger appears in Chinese, Indian and Indonesian folk medicine, but culinary kencur should not be presented as a treatment for pain, cough or any other condition. Studies of concentrated extracts do not establish that the small amounts used in food reproduce those effects.
Nutritional Benefits
Used as a flavouring in teaspoon-sized quantities, sand ginger contributes only trace nutrients. Its worth is aromatic: a modest amount lifts vegetable salads, rice dishes and broths, making lighter food more satisfying. The rhizome's essential oil holds compounds such as borneol, camphene, cineole and ethyl cinnamate that account for its camphorous scent — part of its chemistry, not a verified health promise. Enjoy it as a condiment rather than a supplement.
How to Prepare
- Choose: Look for firm, plump, dark-brown rhizomes without mould or soft spots; a fresh cut should smell strongly camphorous.
- Wash and trim: Rinse well with a brush and scrape away any fibrous outer layer. The small fingers can be gritty, so cleaning matters more than peeling.
-
Cut for the dish:
- For fresh pastes, chop small and pound or grate finely so it blends evenly
- For dressings, grate very fine — sand ginger has almost no coarse fibre, so it disperses well
- For soups and broths, crush a small piece lightly and remove it before serving
- Use a light hand: Because the flavour is concentrated and slightly bitter, start with less than you think and add more after tasting.
Storage
Wrap unwashed rhizomes loosely and refrigerate for a week or two, or freeze whole. Dried and ground kencur is convenient but noticeably different from fresh, so adjust quantities if substituting.

Suggested applications: an Indonesian-style peanut dressing for steamed greens, a kencur-and-coconut vegetable urap, savoury rice-cracker seasoning, and a warm beras-kencur-style drink.
Varieties
- Sand ginger is usually treated as a single culinary type, with the fresh rhizome and the dried, ground form seen as two different ingredients for different dishes.
- Greater galangal (Alpinia galanga) and lesser galangal (Alpinia officinarum) are separate species — the names collide, but not the plants.
- Fingerroot (Boesenbergia rotunda) is a closer cousin in the same family and is likewise sold whole and fresh.
Fun Facts
- Despite "ginger" in the name, sand ginger is a Kaempferia, not a Zingiber — a different genus from ordinary ginger.
- It is one of several rhizomes loosely called "galangal," yet true galangal is Alpinia galanga.
- Sand ginger lacks the upright leafy stem that galangal and ginger have, spreading its leaves flat across the ground.
- In Java its dried powder is stirred into rice flour to make a drink, not a dish — beras kencur.
- The same aromatic rhizome appears fresh in Indonesian spice pastes and dried in Chinese savoury cooking.
