Preparation: Start by finely chopping the onions. These will serve as the base of your curry. Be sure to chop them into even pieces for a smooth, consistent texture. Once the onions are prepared, peel and chop any additional vegetables you'd like to include in the curry. Garlic and ginger should also be finely minced to release their rich flavors. Set everything aside and get ready to cook. (Time taken: 10 minutes)
Sautéing: Heat a pan or wok on medium heat and add your choice of oil. Allow it to heat up slightly. Once the oil is hot, add the finely chopped onions to the pan. Stir them gently, allowing the onions to cook down and turn translucent, which takes about 3 to 5 minutes. You'll begin to notice the delightful aroma of caramelized onions filling the kitchen. This step is crucial for developing a rich base. (Time taken: 5 minutes)
Adding Spices: Once the onions have softened and slightly browned, it’s time to add the spices. Sprinkle in turmeric, cumin, coriander, and a pinch of chili powder, depending on your spice preference. Stir everything together, ensuring the spices coat the onions evenly. The heat from the pan will help release the fragrant oils from the spices, creating a mouthwatering aroma that fills the air. Continue to sauté the mixture for another 2 to 3 minutes. (Time taken: 3 minutes)
Incorporating Tomatoes: Next, add chopped tomatoes to the pan. Stir them into the onion-spice mixture. The tomatoes will break down and release their juices, forming the base of the curry sauce. Allow the tomatoes to cook down until they soften and merge with the onions, creating a smooth, thick texture. The combination of onions and tomatoes creates a savory depth of flavor in the curry. (Time taken: 5 minutes)
Simmering: Once the tomatoes have fully cooked, add a small amount of water to the pan to adjust the consistency of the curry. You can make the curry thick or thin depending on your preference. Stir everything together, ensuring the sauce is well mixed. Bring the curry to a gentle simmer and let it cook for about 10 to 15 minutes, allowing all the flavors to meld and develop. This is when the curry truly comes to life. (Time taken: 15 minutes)
Final Touches: As the curry simmers, taste the sauce and adjust the seasoning if needed. You can add more salt, spice, or even a touch of sugar to balance the acidity of the tomatoes. For a rich and smooth finish, you can also stir in a splash of cream or coconut milk, depending on your preference. Let it simmer for a few more minutes to bring everything together. (Time taken: 5 minutes)
Serving: Once your onion curry has reached the perfect consistency and flavor balance, remove it from the heat. Serve it hot with freshly steamed rice, roti, or naan bread. Garnish with fresh coriander leaves for a burst of color and freshness. This simple yet flavorful onion curry is now ready to be enjoyed. (Time taken: 2 minutes)
