What is Gond Katira?
Gond Katira, also known as Tragacanth Gum, is a natural edible gum widely used in Indian summer beverages. Once soaked, it expands into a jelly-like texture that helps cool the body from within.
Traditionally, gond katira is consumed during the summer months to:
- Prevent heat exhaustion
- Support hydration
- Promote digestive health
- Provide natural cooling effects
Its mild flavor makes it perfect for drinks, falooda, sherbets, and summer coolers.

Benefits include:
- High in fiber

Ingredients or the Watermelon Cooler
Juicy sweet watermelon - There are various different ways you can pick sweet juicy water melons. Here is a great article by Serious Eats that explains it in detail.
Gond Katira - Aso known as Tragacanth Gum, is a natural edible gum widely used in Indian summer beverages. It helps to cool your body and promotes digestive health.
Basil seeds - Can easily be confused with chia seeds. These are high in fiber, supports digestive system and provides a cooling effect.
Kala Namak - A pinch of salt helps to enhance the sweetness of the watermelon. You can either use the regular salt or use black salt (kala namak). Kala namak has a distinctive savory, sulfurous flavor. It adds Umami depth and a slightly smoky flavor.
Chaat Masala - Chaat masala is a tangy, savory Indian spice blend that instantly adds a burst of flavor to fruits, snacks, salads, and drinks.
Fresh Mint Leaves - Watermelon and mint leaves always works together beautifully. In both drinks and salad.
Coconut water - You can make this watermelon cooler with water too but during peak summer days I prefer coconut water.
Steps to prepare

STEP 1 - Soak Basil Seeds and Gond Katira
Add 1 tablespoon basil seeds to 1 cup water. Let soak for 15 to 20 minutes.The seeds will swell and develop a gelatinous coating.
Soak 1 teaspoon gond katira in 1 cup water overnight. By morning, it will expand significantly and become jelly-like or shaved ice.

STEP 2 – Either blend the watermelon with a few fresh mint leaves or muddle them directly in a serving glass. For an ultra-smooth and refreshing drink, blend the watermelon first and strain the juice before adding the remaining ingredients.
STEP 3 – Add the soaked basil seeds and gond katira, followed by kala namak and chaat masala.
Kala namak (Indian black salt) and chaat masala are popular Indian seasonings that add a tangy, savory flavor to the cooler. If you don't have them on hand, simply use regular salt and a squeeze of fresh lemon juice instead.
STEP 4 – Fill the glass with ice cubes, then pour in coconut water for a naturally sweet and hydrating drink. You can also use regular chilled water if preferred.
STEP 5 – Stir everything well and give it a taste. Adjust the seasoning with a little more salt if needed, then serve immediately and enjoy this cooling summer refreshment.
