🤔 What Is Galangal?
Galangal is a rhizome (root) closely related to ginger and turmeric, with a unique, pungent flavor that is sharp, citrusy, and pine-like. It has a tough, woody texture and pale flesh, and it is an essential aromatic ingredient in many Southeast Asian cuisines, especially Thai soups and curry pastes.

The Triple-S Method
Master the three essential steps for food success:
🛒 SHOP SMART: Selection Guide
- Choose galangal with firm, taut skin.
- The root should feel heavy and solid, not light or soft.
- Avoid any pieces with wrinkled skin, soft spots, or signs of mold.
Appearance
Look for rhizomes with smooth skin that has a pinkish or pale yellowish hue. The flesh inside should be a creamy white or pale yellow.
Smell
Fresh galangal has a sharp, medicinal, and citrusy aroma. It is distinctly different from the spicy scent of ginger.
Texture
The root should be very hard and woody. If it is soft or pliable, it is no longer fresh.
Common Varieties / Types
There are two main types of galangal used in cooking.
- Greater Galangal (Alpinia galanga): This is the most common variety, with a pungent, pine-like flavor. It is larger and used widely in Thai and Indonesian cooking.
- Lesser Galangal (Alpinia officinarum): Smaller and more pungent, with a sharper, more peppery flavor. It is more common in Chinese medicine and cooking.
📅 Seasonal Buying Guide
North America (USA/Canada)
Galangal is a tropical plant and is not grown commercially on a large scale in these regions. It is available year-round in Asian grocery stores and specialty markets as an import.
Europe
Primarily available as an import from Southeast Asia, found year-round in Asian and specialty food shops.
Australia/New Zealand
Grown in tropical parts of Australia, fresh galangal is available in many markets year-round.
Tropical/Subtropical Regions
Galangal is native to Southeast Asia and is a common, year-round ingredient in local markets.
Seasonal Quality Variations
As a tropical rhizome, there is little to no seasonal variation in the quality of galangal found in stores.
❄ STORE FRESH: Storage Guide
- Whole, unpeeled: Refrigerator for 2-3 weeks.
- Cut or peeled: Refrigerator, tightly wrapped, for 1 week.
- Best method for long-term: Freeze it.
Storage Method Details
Refrigerator (Whole): Store an unpeeled piece of galangal root in a plastic bag or airtight container in the crisper drawer of your refrigerator. It will stay fresh for several weeks.
Refrigerator (Cut): Once cut or peeled, wrap the exposed end tightly in plastic wrap to prevent it from drying out. It should be used within a week.
The tough outer skin of the galangal rhizome protects the flesh from dehydration. The cool, stable environment of the refrigerator slows down moisture loss and prevents mold growth, preserving its pungent flavor.
Ethylene Production/Sensitivity
Galangal is not a significant producer of ethylene gas and is not sensitive to it.
Revival Techniques
A slightly shriveled piece of galangal can still be used for cooking. While it may have lost some moisture, its potent flavor will still be present when it is sliced or grated into a dish.
⚠ STAY SAFE: Food Safety Tips
- Max Time at Room Temp: 2 Hours (once cut)
Understanding Food Safety Rules
As a root vegetable that grows in soil, galangal must be washed and scrubbed thoroughly before use. The FDA recommends using a produce brush under running water to remove any dirt and contaminants.
Reheating Methods
Galangal is an aromatic used for flavor and is not typically reheated on its own.
Date Labels Explained
Fresh galangal does not have date labels. Judge its freshness by its firmness and the condition of its skin.
Allergen Information
- Contains: None of the top 9 allergens.
⚠ Special Safety Considerations
The woody texture of mature galangal makes it difficult to chew. It is typically sliced into “coins” to infuse flavor into soups and curries, and these pieces are removed before eating.
Pesticide Residue Information
The edible part of galangal grows underground, but the FDA still recommends washing and scrubbing the skin thoroughly before peeling to remove any soil-borne contaminants.
🧊 Freezing & Thawing Guide
Freezing Effects & Preparation
Galangal freezes exceptionally well with very little loss of its aromatic flavor. Freezing also makes it easier to grate.
To freeze, simply wash and dry the whole, unpeeled root and place it in a freezer-safe bag. You can also slice it into coins first for convenience. It will last for a year or more.
Recommended Thawing Methods
There is no need to thaw galangal before use. You can grate the frozen root directly into your dish with a microplane. This is often easier than grating it fresh.
Not Recommended
Thawing is generally unnecessary. If you must thaw it, do so in the refrigerator.
🔥 Cooking Information
Quick Cooking Reference
Galangal is used as an aromatic to build a flavor base. It is rarely the star of the dish itself. Its tough texture requires it to be prepared properly.
| Method | Prep Style | Best Use |
|---|---|---|
| Slicing | Thin “coins” | Infusing soups and broths (e.g., Tom Yum) |
| Pounding/Grating | Minced/Pasted | Creating the base for curry pastes |
Cooking Methods for Galangal
Galangal must be peeled before use, which can be done with a spoon or a sharp paring knife.
Slicing for Infusion
For soups like Tom Kha Gai, slice the woody galangal root into thin coins. Add these to the broth to infuse it with their unique flavor, but advise diners to remove them before eating.
Pounding into Paste
For Thai curry pastes, finely chop or grate the galangal and then pound it in a mortar and pestle with other aromatics like lemongrass, garlic, and chilies to create a fragrant base.

🌎 Sustainability & Sourcing
Galangal is a hardy tropical plant that is sustainable to grow within its native climates. For consumers outside of these regions, the main environmental impact is from the transportation required to import it.
Sourcing from Asian markets that have a high turnover and efficient supply chains can ensure the freshest product.
🔄 Substitutions & Alternatives
Fresh ginger is the most common substitute for galangal, but it is not a perfect match. Galangal has a much more citrusy and piney flavor, while ginger is spicier and more pungent.
To better approximate the flavor of galangal, use fresh ginger combined with a small amount of lemon zest and black pepper.
🔪 Recommended Tools
A sharp, sturdy knife is needed to slice through the tough, woody rhizome. A spoon can be an effective tool for scraping off the thin skin, just like with ginger. A microplane grater is excellent for grating frozen galangal.
💡 Pro Tips
♻ Waste Reduction
Because it can be hard to find, buy a large piece of galangal when you see it and freeze it. It lasts for over a year in the freezer and is often easier to grate or slice when frozen solid.
✨ How to Revive It
There is no effective way to revive galangal that has become soft or moldy; it should be discarded.
❓ FAQ
A: No, they are related but are two different rhizomes. Galangal has a sharp, citrusy, almost pine-like flavor, while ginger is pungent, spicy, and sweet. They are not interchangeable in recipes.
