Kulambu Milagai Thool – Homemade South Indian Kulambu Chilli Powder

Heat a heavy-bottomed kadai or iron pan on low to medium flame. Keep the flame consistently low throughout the roasting process to avoid burning the spices, which will make the powder bitter. Dry roasting on a low flame draws out the natural oils and deepens the aroma of each spice beautifully.

First, dry roast the coriander seeds in the pan without any oil for 3 to 4 minutes, stirring continuously until they turn light golden and release a nutty aroma. Transfer to a large plate and spread them out to cool completely. Do not leave them in the hot pan as they will continue to cook and may burn.

In the same pan, dry roast the chana dal and urad dal together, stirring often, until they turn light golden brown and smell toasty. This takes about 2 to 3 minutes on low flame. Transfer to the cooling plate. These dals add a wonderful thickness and a mild nutty depth to the finished kulambu powder.

Add cumin seeds and black pepper to the pan and dry roast for 1 to 2 minutes until the cumin turns aromatic and slightly darker. Transfer to the cooling plate. Next, roast the fennel seeds for about 1 minute until fragrant. Fennel gives the kulambu powder its signature sweet warmth that balances the heat perfectly.

Roast the cinnamon, cloves, stone flower, and marathi mokku together for 1 to 2 minutes on low flame, stirring gently until fragrant. These whole spices are what elevate this kulambu powder above ordinary chilli powder, giving it a complex, restaurant-quality depth that makes every curry taste truly special and aromatic.

Add a few drops of oil to the pan and lightly fry the curry leaves until they become crisp and completely dry, about 1 minute. Remove and set aside. Crispy curry leaves grind well and infuse the powder with their unmistakable South Indian fragrance that is essential to authentic Tamil kulambu flavour.

Now lightly toast both types of dried red chillies in the pan with a tiny drop of oil on low flame for 2 to 3 minutes, stirring constantly, until they puff up slightly and deepen in colour. Be very careful not to burn them. The Kashmiri chillies give a beautiful deep red colour while the regular chillies provide the heat.

Allow all the roasted ingredients to cool down completely to room temperature before grinding. This is a very important step. Grinding warm spices in a mixer generates heat and moisture which affects the quality, texture, and shelf life of the powder. Spread everything on a large plate and wait at least 20 to 30 minutes.

Once fully cooled, add all the roasted ingredients along with the turmeric powder into a mixer grinder or take them to a flour mill for a finer grind. Grind in batches if needed to avoid overloading the jar. Pulse first to break everything down, then grind continuously until you get a smooth, fine powder.

Sieve the ground powder through a fine mesh sieve to remove any coarse bits. Regrind any coarse pieces that remain in the sieve. Sifting gives you an even, smooth texture that dissolves beautifully into gravies without any gritty bits. Your fragrant homemade kulambu milagai thool is now ready to use and store.

Transfer the cooled powder into a clean, completely dry airtight glass jar or steel container. Store in a cool, dry place away from direct sunlight and moisture. The powder stays fresh and vibrant for up to 2 to 3 months at room temperature. For longer shelf life up to 6 months, store in the refrigerator in an airtight container.
