Instructions

Step 1: Prepare the Spice Paste

Dry roast the spices: Start by heating a kadai (a traditional Indian wok) over medium heat. Add fennel seeds and dry red chilies to the pan and dry roast them until they release a fragrant aroma. This should take about 1-2 minutes.
Grind the masala: Once roasted, remove the spices from the heat and allow them to cool for a few minutes. Next, transfer the spices to a mixie jar or a blender. Add the chopped coconut to the jar and blend the mixture into a smooth paste using a little water as needed. Set this masala paste aside.

Step 2: Make the Tempering

Heat the oil: In the same kadai, heat sesame oil over medium heat. Once the oil is hot, add fennel seeds and curry leaves, letting them sizzle for about 30 seconds. This will infuse the oil with rich flavors.
Sauté the onions and tomatoes: Now add the thinly sliced onions to the pan and sauté until they turn golden brown and translucent. Next, add the chopped tomatoes and cook on low heat, stirring occasionally. The tomatoes should soften and break down into a thick, pulpy mixture.
Add turmeric and salt: Sprinkle turmeric powder and salt over the onion-tomato mixture. Stir well to combine and cook for another 2 minutes.

Step 3: Cook the Chettinad Vengaya Kosu

Add water: Pour 1 cup of water into the kadai and bring the mixture to a gentle boil.
Incorporate the masala: Once the water starts to simmer, add the prepared ground masala paste and stir it well into the curry. Allow the curry to cook for another 3-4 minutes, letting all the flavors meld together.
Adjust seasoning: Taste and adjust the salt or spice level according to your preference. You can add more water if you prefer a thinner consistency.

Step 4: Garnish and Serve

Turn off the heat: After the curry has simmered for a few minutes, turn off the heat.
Garnish: Transfer the Chettinad Vengaya Kosu to a serving dish and garnish with finely chopped coriander leaves.
Serve: Serve the curry hot with steamed Biryani, Ven Pongal, or Onion Rava Dosa for a comforting and hearty meal. This dish also pairs well with rice or any other South Indian staples.

Serving Suggestions

Chettinad Vengaya Kosu is a versatile dish that can complement many traditional South Indian meals. Here are some suggestions for serving it:

With Biryani: The spicy and tangy flavors of the curry perfectly balance out the richness of a Biryani. It can be served alongside to add moisture and enhance the overall flavor experience.
With Ven Pongal: This soft, mildly seasoned rice-lentil dish makes an excellent pair for the bold flavors of the kosu. Serve it for a filling breakfast or a light lunch.
With Onion Rava Dosa: The crispiness of Onion Rava Dosa combined with the flavorful curry makes for a delightful meal. It’s a great choice for a weeknight dinner when you want something simple yet satisfying.

Cooking Tips

Adjusting spice levels: The quantity of dry red chilies can be adjusted based on your spice tolerance. If you prefer a milder curry, reduce the number of chilies, or opt for milder varieties like Kashmiri red chilies, which provide color without too much heat.
Consistency of the curry: If you prefer a thicker gravy, reduce the amount of water added in Step 3. Conversely, for a thinner consistency, add more water and simmer the curry longer to blend the flavors.
Adding vegetables: Although the traditional version focuses on onions, you can add vegetables like potatoes, carrots, or peas to make it more substantial.

Variations

With Potatoes: For a heartier version, cubed potatoes can be added to the curry. Boil the potatoes separately and add them to the curry along with the masala paste.
With Drumsticks: Drumsticks (Moringa) are a popular addition to many South Indian gravies. Add drumsticks while cooking the onions and tomatoes to enjoy a traditional variation.
Without Coconut: For a lighter version, you can skip the coconut and focus more on the spices. Simply increase the quantity of onions and tomatoes to thicken the curry naturally.

Storage Instructions

Refrigeration: Chettinad Vengaya Kosu can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in a pan or microwave before serving.
Freezing: You can freeze this curry for up to 2 months. Store it in a freezer-safe container, and thaw it overnight in the refrigerator before reheating.
