Nam Krajeab Recipe_Feature

You’ve probably heard of green tea and black tea, but have you ever tried Nam Krajeab, or Thai Roselle Tea? It’s not just a refreshing drink, it’s a tradition steeped in Thai culture.

Nam Krajeab recipe, also known as Thai Roselle Tea, is a delightful and vibrant beverage hailing from Thailand and other parts of Southeast Asia. This tea is crafted from the deep red calyces of the roselle plant (Hibiscus sabdariffa) and is cherished for its unique blend of tartness and sweetness.

There’s much to learn about this vibrant red tea – from its unique taste profile to its health benefits. So, let’s explore everything there is to know about Nam Krajeab.

The Origin of Nam Krajeab Recipe

You’d be intrigued to know that the original Nam Krajeab recipe traces back to ancient Thai traditions. This vibrant, tangy beverage, crafted from the crimson calyces of the Roselle plant, has been a staple in Thai households for centuries. It’s steeped in history and culture, much like the country itself.

In the olden days, you’d have found Thai people sipping on Nam Krajeab as they sought refuge from the sweltering heat. The recipe, passed down through generations, has remained relatively unchanged. It’s a simple process: the calyces are boiled until they release their ruby-red color and tart flavor. Then, it’s sweetened with cane sugar to balance the sourness.

But don’t mistake its simplicity for lack of depth. Each sip of Nam Krajeab is a nod to the past, a testament to the Thai’s resourcefulness and respect for nature. You’re not just drinking a thirst-quencher, you’re partaking in a tradition that has stood the test of time.

Understanding the Roselle Plant

Known scientifically as Hibiscus Sabdariffa, the Roselle plant is native to West Africa but has found its way to Southeast Asia, especially Thailand. In appearance, it’s an attractive shrub, reaching heights of up to 2.5 meters, often decorated with vibrant red flowers that give it a striking look.

The real magic, however, lies in its calyces, the part of the plant just beneath the flowers. These are what you use to make the Nam Krajeab tea. They’re usually a dark, ruby-red color and have a tart taste, somewhat like cranberry. When boiled, they release a deep red color that’s characteristic of the tea.

But it’s not just about the taste and color. Roselle is packed full of health benefits. It’s rich in Vitamin C, has anti-inflammatory properties, and helps in lowering blood pressure. So, not only does Nam Krajeab offer a unique taste experience, but it also provides a healthy boost to your body.

Servings 4
Calories 70 kcal


  • Large pot You'll need a large pot to boil the roselle calyces. Ensure it's big enough to accommodate the calyces and water comfortably.
  • Fine Mesh Strainer or Cheesecloth: To strain the boiled roselle calyces from the liquid, you'll need either a fine mesh strainer or cheesecloth. A fine mesh strainer is more convenient for everyday use, while cheesecloth can be used for a finer strain if desired.
  • Measuring Cups Use measuring cups to accurately measure the dried roselle calyces, water, and sugar.
  • Stirring Spoon A long-handled stirring spoon will help you mix the sugar into the tea and stir the mixture as needed.
  • Glasses: To serve the tea, you'll need glasses or cups. If you prefer your tea cold, you can also use glasses with ice cubes.
  • Optional: Fresh Mint Leaves: If you choose to garnish your tea with fresh mint leaves, have them ready as well.
  • Optional: Refrigerator or Ice Maker: If you plan to serve the tea cold, you'll need a refrigerator to chill it before serving or an ice maker to make ice cubes.


  • 1 cup dried roselle calyces
  • 4 cups water
  • 3/4 cup sugar (adjust to taste)
  • Ice cubes (optional)
  • Fresh mint leaves for garnish (optional)


Prepare the Roselle Calyces:

  • Start by inspecting the dried roselle calyces for any debris or foreign objects. Rinse them thoroughly under cold running water to remove any impurities.

Boil the Roselle Calyces:

  • In a large pot, bring 4 cups of water to a boil.
  • Add the rinsed roselle calyces to the boiling water.
  • Reduce the heat to medium-low and let the calyces simmer for about 10-15 minutes. You'll notice the calyces start to soften and release their vibrant red color.

Sweeten the Tea:

  • After simmering, remove the pot from the heat.
  • Add sugar to the pot, starting with 1/2 cup and adjusting to your taste preference. Remember that the sweetness level can vary, so you may need to add more or less sugar.
  • Stir the mixture until the sugar completely dissolves.

Strain and Cool:

  • Using a fine mesh strainer or cheesecloth, strain the liquid into another container, separating the liquid from the calyces. You can discard the calyces or save them for other culinary uses.
  • Allow the strained liquid to cool to room temperature. You can speed up the cooling process by placing it in the refrigerator.


  • Once the roselle tea has cooled, you can serve it.
  • Fill glasses with ice cubes if you like your tea cold and refreshing
  • Pour the roselle tea over the ice.
  • Optionally, garnish each glass with fresh mint leaves for added aroma and flavor.
  • Serve your Nam Krajeab and enjoy the tangy and slightly tart flavor of this delicious Thai roselle tea.


  • Fresh vs. Dried Roselle Calyces: While the recipe above uses dried roselle calyces, you can also make this tea using fresh ones if they are available. Fresh calyces may have a slightly different flavor profile and color, so feel free to experiment.
  • Adjusting Sweetness: The amount of sugar you add is highly customizable. Start with a smaller amount and taste the tea before adding more. Remember that it’s easier to add more sugar later if needed, but you can’t easily reduce the sweetness if you’ve added too much.
  • Tartness: If you prefer a more tart flavor, you can increase the amount of roselle calyces or reduce the sugar. The natural tartness of the roselle calyces is a defining feature of this tea.
  • Chilling: If you want to serve the tea cold, you can chill it in the refrigerator before serving. You can also add extra ice cubes to individual glasses for an extra-refreshing experience.
  • Variations: Some variations of Nam Krajeab include adding other flavorings like lemongrass or ginger for a unique twist. Experiment with different herbs and spices to create your own signature roselle tea.
  • Storage: If you have leftover tea, store it in an airtight container in the refrigerator. It should stay fresh for a few days. You can reheat it if you prefer to have it warm.
  • Health Benefits: Roselle tea is known for its potential health benefits, including being rich in antioxidants and vitamin C. It’s often consumed for its purported positive effects on digestion and overall well-being.
  • Calyces for Other Uses: Don’t throw away the boiled calyces after straining. They can be used in jams, jellies, sauces, or even as a flavorful addition to salads.
