Kencur

What is Kencur?

Kaempferia galanga is a monocot plant belonging to the ginger family. Unlike other galangals, this plant grows without an upright stem above the ground. It produces rounded underground rhizomes with a dark brown outer skin. The fresh root and its dried forms are recognized for their distinct, peppery bite with strong camphorous notes. Its green leaves can also be harvested for culinary use. It is one of four distinct roots commonly referred to as galangal across Asian cooking traditions.

Where does Kencur come from?

This spice naturally thrives in open habitats across southern China, Taiwan, India, Cambodia, and Indonesia. Over time, its cultivation spread extensively across Southeast Asia. In regional languages, it acquired diverse local names, being known as kencur in Indonesia, cekur in Malaysia, sha jiang in China, and prâh in Cambodia. While it shares the broader galangal name, it remains a distinct botanical species historically integrated into island Southeast Asian and southern Chinese foodways and domestic trade.

What does Kencur taste like?

The taste of this rhizome is sharp, peppery, and noticeably camphorous. Its aromatic qualities stem from a complex mix of essential oils and chemical constituents. Key compounds include cineol, borneol, camphene, and 3-carene, alongside cinnamaldehyde, ethyl cinnamate, and ethyl p-methoxycinnamate. These terpenes, phenolics, and esters give the root its piercing fragrance, setting it apart from true ginger and ordinary galangal varieties.

How Kencur is used

Cooks use both the subterranean rhizome and the foliage of the plant. In Indonesia, especially within Balinese and Javanese culinary traditions, the fresh or dried root is a fundamental seasoning in savoury dishes. Malay cooks incorporate the fresh leaves directly into herb-laden rice dishes such as nasi ulam. In Chinese cuisine, dried pieces or ground root, sold as sand ginger, season various regional dishes. Thai cooks rarely place it in daily pots, but dried root is traded at herbal counters.

Kencur in the world's kitchens

The spice holds a central place in Javanese and Balinese culinary practices under the name kencur. In Malaysia, where it is known as cekur, its foliage flavors classic rice preparations like nasi ulam. Chinese kitchens utilize the dried root, labelled as sha jiang, for savoury seasoning. Conversely, Thai cooking favors other ginger relatives like krachai over this plant, restricting its presence in Thailand primarily to traditional medicine stalls under names like proh horm or waan horm.

Traditional and medicinal use

Traditional Chinese medicine utilizes the rhizome in decoctions and powders. Alcoholic macerations of the root have traditionally served as a topical liniment for rheumatism. In Indonesia, it forms the foundation of beras kencur, an established jamu health tonic. Historical traditions also note that leaf sap and decoctions were thought to produce hallucinogenic sensations, which researchers link to unidentified essential oil components.

What to use instead of Kencur

Cooks sometimes confuse this plant with lesser galangal, a name that formally applies to Alpinia officinarum. It is also compared to fingerroot, known as krachai in Thailand, though the two are used differently. Unlike other galangal varieties that display tall stems and pale pinkish-brown rhizomes, this species is stemless with dark brown roots.

Meal

This seasoning features prominently in lunchtime and evening rice preparations, such as Malay mixed-herb rice. It is also an essential component in beverages. In Indonesia, powdered dried rhizome is mixed with ground rice flour to create beras kencur, a widespread traditional jamu tonic enjoyed across Java and Bali.
