What Is Kolonjan (Galangal)?

Galangal vs. ginger

Galangal (genus Alpinia) and ginger (genus Zingiber) both belong to the wider ginger family, Zingiberaceae, which is why the two rhizomes look similar at a glance — pale, knobby, fibrous. The flavour is where they part ways: ginger is warm, slightly sweet and cleanly pungent, while galangal is sharper, more citrusy and resinous, with a peppery, almost medicinal edge that many first-time tasters describe as closer to black pepper or pine than to ginger.

Because the two aren't the same plant, they aren't a clean one-for-one substitute in a recipe that specifically calls for galangal's sharper profile — using ginger instead will get you warmth, but not the citrus-pepper character that defines dishes built around kolonjan.

Ground vs. whole kolonjan

Whole dried kolonjan comes as hard, pale slices that need soaking or grinding before use — a slower step, but one that holds the rhizome's aromatic oils longer in storage since less of the cut surface is exposed to air. Ground kolonjan is ready to measure straight into a spice blend or a pot, which is the more practical format for kitchens using it regularly rather than occasionally.

We stock whole kolonjan alongside the ground form through AbdulRahim Mills, so buyers can choose based on how often the spice moves through their kitchen and whether they're set up to grind their own.

Which cuisines call for it

Galangal is a foundational ingredient across Southeast Asian cooking — Thai and Indonesian kitchens in particular use it in curry pastes, soups and aromatic bases, where its sharp, citrusy bite is a defining flavour rather than a background note. Its footprint in Middle Eastern and South Asian cooking is smaller and more specialized: it turns up in some traditional spice blends and, historically, in medieval Arab and Persian cuisine, which is part of why it carries a distinct Arabic name (kolonjan) rather than being referred to only by a transliteration of "galangal."

Preparing whole kolonjan before cooking

Because dried whole kolonjan slices are hard and fibrous, most kitchens soak them in warm water for a stretch before use, which softens the pieces enough to pound, blend or simmer into a dish — a step that's simply skipped when working from the ground form. Some preparations, especially soups and stocks, add the dried slices directly to a long-simmering pot without pre-soaking, letting the extended cooking time do the softening instead.

Either method works; the choice comes down to how a specific recipe or kitchen workflow is set up, and whether the slices themselves need to be strained out and discarded before serving or are meant to soften into the dish entirely.

Ground kolonjan skips all of that preparation, which is exactly why kitchens using it as a regular seasoning — measured into a spice blend by weight rather than added as a distinct ingredient to a single dish — tend to prefer the ready-milled form over managing whole dried slices batch after batch.
