Galangal
Galangal is the spice produced from the rhizomes of two tropical evergreen herbs in the ginger family. Greater galangal is more popular for cooking, and lesser galangal is more often used in traditional medicine.
Greater Galangal: Alpinia galanga
Lesser Galangal: Alpinia officinarum
REGION OF ORIGIN
Southeast Asia. Galangal has flourished for thousands of years in this region’s humid, tropical lowland forests. Greater galangal is believed to be from Java, and lesser galangal most likely originated in southern China.
PART & COLOR
Fresh galangal rhizomes are typically pale beige to orange-brown, sometimes with pinkish or reddish undertones at the nodes. The inside is creamy white. Some greater galangal varieties have a faint pink hue to the inner flesh, whereas lesser galangal's can be a darker orange.
HARVEST
Thriving in many tropical climates with ample rainfall, galangal is cultivated primarily from rhizome divisions, whereby farmers separate mature rhizomes into smaller sections to replant. Each rhizome requires 10-12 months to fully mature. Farmers assess maturity of the underground structures by observing the shoots above-ground. When the long, lance-shaped leaves begin to yellow and die back, the rhizomes have reached peak flavor.
FLAVOR & AROMA PROFILE
Greater galangal is more commonly used in cooking because it's milder and sweeter than its "lesser" cousin. But it’s plenty bold. It has a sharp, citrusy scent that carries notes of pine, earth, and fresh flowers. Grate a fresh rhizome and an intense, peppery pungency will electrify your senses.
On the tongue, galangal is zesty with a spicy warmth. Its heat is more biting than ginger but smoother than chiles, leaving a clean, tingly aftertaste. Hints of a slight soapiness or sourness can emerge as well. It has a unique complexity to it that's rather irreplaceable in the kitchens of Thailand, Indonesia, Malaysia, and Vietnam.
CULINARY USES
Galangal is a pillar of Southeast Asian cuisine. Perhaps its most iconic role is in the Thai soups tom yum and tom kha gai, where its sharp tang is the backbone of the broth. In Indonesia, galangal forms the base of countless spice pastes (bumbu) and marinades because its robust flavor holds up well against strong ingredients.
Fresh galangal is frequently used in curries to infuse meats, but it's especially popular with seafood as its bright heat balances overly fishy flavors. Thinly slice it, bruise chunks, pound it into a paste, or finely grate it with a microplane to unleash its full power.
