Koozh Vathal (Kanji Vathal) - Traditional Tamil Sun-Dried Rice Crackers
Rate this recipe
Koozh Vathal, also known as Kanji Vathal or Arisi Vadagam, is one of the most beloved traditional sun-dried snacks from Tamil Nadu. Made from a simple cooked rice flour porridge seasoned with salt and spices, this vathal is carefully spread on damp cloth and left to dry under the hot summer sun. Once fully dried, these crispy crackers are deep-fried or air-fried to golden perfection and enjoyed as a crunchy side dish with rice meals. This age-old technique of preserving food through sun-drying is a true hallmark of Tamil culinary heritage.
Tamil families across generations have cherished the tradition of making vathal during the peak summer months of April and May when the sun is at its strongest. Grandmothers and mothers would wake up early, prepare the koozh batter, spread it carefully on white cotton cloths laid across rooftops and terraces, and wait patiently for the sun to work its magic. It is more than just a recipe — it is a summer ritual, a bonding moment, and a way to stock up on crispy snacks that last through the monsoon months. Nothing compares to the pride of a Tamil household that makes its own homemade vathal.
What makes this koozh vathal recipe so special is its beautiful simplicity. With just rice flour, water, salt, and a few aromatics like cumin or green chillies, you can create a batch of crackers that last for months in an airtight container. The key to perfect vathal lies in getting the porridge consistency right — it should be smooth, lump-free, and pourable. Always wet the cloth before spreading to ensure the vathal peels off cleanly once dry. Make a big batch during summer and enjoy crispy, golden vathal all year round with your favourite rice and curry.

💡 Tap a step to mark it doneIn a large heavy-bottomed pan or kadai, add 6 cups of water and bring it to a gentle heat over medium flame. Add salt, cumin seeds, asafoetida, and finely chopped green chillies if using. Stir well to combine all the seasonings into the water.
In a separate bowl, dissolve 2 cups of fine rice flour in 1 cup of cold water, whisking thoroughly to remove all lumps. Make sure the mixture is completely smooth and lump-free before adding it to the hot water. This step is crucial for a silky smooth koozh.
Slowly pour the dissolved rice flour mixture into the warm seasoned water while stirring continuously. Keep stirring to prevent lumps from forming at this stage. Turn the flame to medium-low and keep stirring.
Cook the mixture on medium-low flame, stirring constantly, until it thickens into a smooth porridge-like consistency. This will take about 15 to 20 minutes. The koozh should be thick enough to coat the back of a spoon but still pourable. Add sesame seeds if using, and mix well. Remove from flame and allow it to cool slightly for about 10 minutes.
While the koozh cools, prepare your drying setup. Lay clean white cotton cloths on a flat surface such as a rooftop, large tray, or clean floor that receives direct sunlight. Wet the cloths with clean water and wring out excess moisture — the cloth should be damp, not dripping wet. This prevents the vathal from sticking to the cloth when dry.
Using a small ladle or spoon, drop small rounds of the warm koozh mixture onto the damp cloth, spacing them about 2 to 3 cm apart. Each drop should be about the size of a small coin, roughly 3 to 4 cm in diameter. Work quickly and evenly.
Place the cloth with the vathal under strong direct sunlight. Allow them to dry for one full day. By evening, gently check if they have dried enough to be flipped. If they peel off easily, flip each vathal and allow the other side to dry on the second day. If they are still wet, leave them until the next morning.
Continue sun-drying for 2 to 3 full days until the vathal is completely dry, hard, and crisp with no moisture remaining. Fully dried vathal will feel very light and will sound hollow when tapped. Peel them gently off the cloth and allow to air for a couple of hours before storing.
To store, place the completely dried vathal in an airtight glass jar or container. They can be stored at room temperature for up to 3 to 4 months in a cool dry place. Keep away from moisture to maintain their shelf life.
To fry and serve, heat oil in a deep kadai on high flame. Once the oil is hot enough (test by dropping a small piece — it should puff up immediately), add a few vathal at a time and fry for 20 to 30 seconds until they puff up, turn golden, and become crispy. Remove and drain on paper towels. Serve immediately as a crunchy side dish with rice, sambar, or curd rice.
Tips and Tricks
- Always wet the drying cloth before spreading the koozh mixture — this is the most important step to ensure the dried vathal peels off cleanly without breaking or sticking to the cloth.
- Make sure the rice flour porridge (koozh) is completely lump-free before spreading. Dissolving the flour in cold water before adding to warm water prevents lumps from forming during cooking.
- Summer months between April and June are ideal for making vathal when sunlight is strongest. Strong direct sunlight ensures the vathal dries evenly and completely within 2 to 3 days, reducing the risk of mould forming.
- Fry the dried vathal in very hot oil so they puff up quickly and stay crispy. Frying in low or medium oil will result in oily, flat, and chewy vathal instead of the desired light and crunchy texture.
- You can customise the flavour by adding crushed black pepper, dried ginger powder, or curry leaves to the koozh for different regional variations of this classic Tamil vathal.
