Greater Galangal (Alpinia Galanga)

Historically, lesser galangal enjoyed popularity in European medieval cooking, though its culinary use today is primarily concentrated in Asia . In traditional Asian medicine, it continues to be valued for its digestive and stimulant properties. The fact that lesser galangal was once a common ingredient in Europe during the Middle Ages, but its use has since diminished, offers an interesting historical perspective. This historical tidbit might resonate with readers and highlight the dynamic nature of culinary trends.

A Culinary Journey: Exploring Galangal in Southeast Asian Dishes

Galangal root offers a complex flavor profile that is often described as spicy, peppery, and slightly citrusy, with underlying notes of pine or earth. This unique combination makes it an indispensable ingredient in many Southeast Asian cuisines.  

Thailand

In Thai cooking, galangal, known as “kha,” is a key aromatic in iconic soups like Tom Yum and Tom Kha Gai , where it infuses a distinct fragrance and a slightly medicinal undertone. It’s also a fundamental component of many Thai curry pastes, including green, red, and yellow varieties , contributing to their layered and nuanced flavors. The aroma of galangal is often likened to a “pine forest,” providing a sensory cue that helps distinguish it from ginger. This vivid description can create a stronger sensory connection for US readers, making its flavor profile more relatable and appealing.  

Indonesia

In Indonesian cuisine, galangal, or “Lengkuas,” plays a significant role in dishes like Rendang, a rich and flavorful beef stew, and Soto, a traditional soup. It’s also featured prominently in Ayam Goreng Lengkuas, a flavorful galangal fried chicken. Galangal’s aromatic qualities are often used to enhance the overall flavor and even help deodorize meats.  

Malaysia

Malaysian cuisine also embraces galangal, known locally as “Lengkuas,” as a key ingredient in dishes like Laksa, a spicy noodle soup, and various curries and stews. It’s often pounded into a paste with other herbs and spices to create a flavorful base for these dishes. The fact that galangal is known as “Lengkuas” in both Indonesia and Malaysia is a valuable piece of information for those exploring these cuisines.  

Flavor Profile: Galangal vs. Ginger vs. Turmeric

While all three belong to the ginger family, their flavor profiles are distinctly different. Galangal offers a peppery, citrusy, and slightly piney or earthy taste, while ginger is known for its fresh, spicy, and slightly sweet notes. Turmeric, on the other hand, has a warm, earthy, and somewhat bitter flavor. Due to these differences, they are generally not interchangeable in recipes.

Bringing Galangal Home: Selection, Storage, and Preparation Tips

Ready to explore galangal in your own kitchen? Here’s what you need to know about selecting, storing, and preparing this flavorful root.

Selecting Fresh Galangal

When choosing fresh galangal, look for roots that are firm and heavy for their size, with a smooth, relatively unblemished pale skin. Slight papery rings and small, round “eyes” on the skin are normal . Avoid roots that feel soft, have moldy spots, or show overly wet or darkened cut sections . You can typically find fresh galangal in Asian markets and sometimes in the international aisle of well-stocked grocery stores, often labeled as Thai or Siamese ginger .  

Storing Fresh Galangal

To keep fresh galangal at its best, store it in the refrigerator, loosely wrapped in plastic wrap or in a plastic bag with a damp cloth, for up to a few weeks . For longer storage, consider freezing it. Slice the galangal thinly and lay the slices in a single layer on a tray in the freezer. Once frozen, transfer them to a freezer bag to prevent sticking. Frozen galangal can last for 2-3 months .  

Preparing Fresh Galangal

Preparing galangal is similar to preparing ginger. You can peel it using a paring knife or vegetable peeler . Due to its fibrous texture, it’s often thinly sliced for soups and broths, where it infuses its flavor and is then discarded . For salads or dressings, it can be finely minced in small quantities. Galangal can also be ground into a paste for curries, often with other herbs and spices . Keep in mind that galangal is generally tougher and more fibrous than ginger, making grating more challenging .  

Using Dried and Powdered Galangal

Dried galangal is available in slices, chips, or powdered form . Dried slices can be rehydrated by soaking in warm water and are suitable for soups and stews, though they require a longer infusion time than fresh galangal . Powdered galangal has a less intense flavor and is often used in curries, spice blends, and occasionally in baked goods . Use dried and powdered galangal sparingly as their flavor can be quite concentrated . For convenience, you might also find frozen galangal or galangal paste in some specialty stores .
