How to Use Galangal in Cooking

Galangal, a rhizome related to ginger, is an essential ingredient in Southeast Asian cuisine, treasured for its ability to impart a unique flavor to dishes.

Known scientifically as Alpinia galanga, it belongs to the Zingiberaceae family and stands out due to its sharp, citrusy notes and slightly piney aroma.

Unlike its more widely used cousin ginger, galangal brings to the table a warm, earthy characteristic that is not easily replicated, making it a valuable component in a variety of recipes.

When cooking with galangal, you’ll find it most commonly used in curries, stir-fries, soups, and stews.

Its bold flavor profile means that a little goes a long way in enhancing the overall taste of your dish.

To fully harness its potential, it’s important to prepare galangal properly.

Starting with a fresh piece, you should clean it thoroughly, peel its skin, and depending on the dish, you can mince, slice, or grind it to incorporate into your recipes.

Understanding Galangal

When embarking on culinary explorations through Southeast Asian cuisine, you’ll find that galangal is a cornerstone ingredient with distinctive flavor and aromatic presence.

It’s key to differentiate the varieties available and to understand its relation to ginger to utilize galangal effectively in your cooking.

Varieties of Galangal

Galangal is a member of the Zingiberaceae family and comes primarily in two varieties that you might encounter:

  • Greater Galangal (Alpinia Galanga): Often referred to as Thai or Siamese ginger, this is the most common type found in Thai and Indonesian cooking. It is larger and has a lighter skin with a more pronounced flavor.
  • Lesser Galangal (Alpinia officinarum): This variety is smaller with a darker skin and packs a spicier punch, used more often in medicinal applications rather than culinary.

Both fresh and dried galangal is used in Southeast Asian cuisine, with fresh galangal imparting a more vibrant taste compared to the subtler flavors offered by the dried form.

Galangal vs. Ginger

Though galangal and ginger are akin, belonging to the same botanical family, they exhibit notable differences:

  • Flavor: Galangal carries a sharp, citrusy undertone with earthy nuances, whereas ginger offers a warmer, more pungent bite.
  • Aroma: The aroma of galangal can be described as fresh and piney, in contrast to the more robust and spicy scent of ginger.
  • Usage: While ginger can be used more liberally, galangal has a stronger flavor profile, so it is typically used sparingly to avoid overpowering the dish.

Preparation Basics

When using galangal in your cooking, starting with the right preparation methods is essential to extract its best flavor and make it easy to incorporate into dishes.

How to Peel and Cut Galangal

To prepare fresh galangal, begin by washing the root thoroughly.

You need a strong, sharp knife because the root is quite dense and fibrous.

Carefully peel the outer layer of the skin to expose the lighter flesh. To peel, either use a vegetable peeler or scrape the skin off with the edge of a spoon.

Once peeled, it’s time to cut the galangal.

For most recipes, thinly slicing the galangal is the preferred method as it exposes more surface area, which releases more flavor during cooking.

If you need to mince the galangal, slice it first, then rock your knife over the slices until they’re finely chopped.

Storing Galangal

Proper storage of galangal ensures it stays fresh and retains its pungent flavor for longer.

If you plan to use the galangal within a week, wrap it in a paper towel, place it in a plastic bag, and store it in the refrigerator’s crisper drawer.

For longer storage, freezing galangal is an excellent option.

You can freeze it whole, sliced, or minced.

When freezing, lay the pieces on a baking sheet spaced apart; once frozen, transfer them to a freezer bag to prevent clumping.

Frozen galangal can be used directly in your cooking without thawing.

If you have dehydrated or powdered galangal, store it in a cool, dark place in an airtight container to protect its aromatic oils.

Culinary Uses of Galangal

Galangal, with its spicy, citrusy, and earthy flavors, is a cornerstone in Southeast Asian cuisine, particularly in Thai, Indonesian, Malaysian, and Cambodian dishes.

Knowing how to incorporate this pungent rhizome can transform your curries, soups, and other dishes with its distinctive peppery kick.

Incorporating Galangal into Curries

When preparing Thai curries, it’s essential to use fresh galangal to achieve the depth of flavor typical to Southeast Asian cuisine.

Grate or finely mince galangal before adding it to your curry paste.

This base typically also includes other aromatics such as shallots, garlic, and lemongrass.

Cooking this paste at the start of your dish will release the robust flavors of galangal, infusing your curry with its signature warm and zesty notes.

  • For a traditional touch:
    • Grate 1-2 teaspoons of fresh galangal for a standard-sized pot of curry.
    • Combine with other curry ingredients like lemongrass and chilies.

Soups and Stews with Galangal

Galangal is a must-have for authentic Tom Yum and Tom Kha soups, contributing its bold profile without overwhelming the delicate balance of the broth.

Slice galangal into thin discs and simmer them in the soup or stew to infuse the liquid with its flavor.

Remember to inform diners about the firm pieces, as they are usually not meant to be consumed directly.

  • For a hearty soup:
    • Add a couple of slices of galangal into your broth and continue to simmer for at least 10 minutes.
    • Pair galangal with coconut milk for the creamy and contrasting base of Tom Kha.

Other Galangal-Infused Dishes

While most commonly associated with curries and soups, galangal also enhances stir-fries and other dishes with its savory spiciness.

Use it sparingly to add a punch of flavor to vegetable or meat stir-fries. Its robust taste stands up to strong flavors, making it a versatile addition to many Southeast Asian dishes beyond just curries and broths.

  • For a quick stir-fry:
    • Finely chop or grind a small amount of galangal and toss it into your stir-fry in the last few minutes of cooking.
    • Balance its pungent note with a touch of sweetness or acidity from palm sugar or tamarind.
