Tips for Making Onion Chutney
To make a flavorful South Indian onion chutney, start by heating oil until it is hot enough to release aromas from the spices. Sauté onions until they turn soft and slightly golden to bring out their natural sweetness. Adding dried red chilies carefully ensures a spicy kick without overpowering the chutney. Garlic and tomatoes enhance the depth and balance of flavors, but you can skip tomatoes if you prefer a pure onion chutney. Mixing in turmeric, cumin seeds, and fresh coriander leaves just before finishing adds earthy notes and freshness. For the authentic tadka, temper mustard seeds, chana dal, and curry leaves in hot oil and pour it over the ground chutney to intensify aroma and taste. Stir gently and serve this homemade spicy onion chutney as a side with dosa, idli, upma, or even rice for a perfect South Indian meal.
