Onion Tomato Chutney/ Tomato Chutney for Idli

Onion Tomato Chutney is a delicious spicy and tangy chutney that goes well with Idlis and Dosas. This recipe for Onion Tomato Chutney is adapted from Chettinad style Tomato Chutney and is finger licking good. You will love the delicious flavors that will linger in your mouth for long! Chettinad cuisine has strong vibrant flavours, as they use selected fragrant spices in their curries. Chettinad Chicken Curry is another chettinad delicacy in my recipe collection.

Coconut chutney, sambar and spicy tomato chutney are best combinations with Idli. Idli and Dosas make healthy and nutritious breakfast. Kids love variety breakfast so to please them I make Pizza Dosas, cheese Dosas, stuffed Idlis, Fried Idli in Curd etc. Kids would love this bright colored Tomato chutney with their Mini Idlis.

I first tried tomato chutney for my cousin, Sunchi, when he came down to visit me. Although he was happy with the result, I was always on the lookout for a better Onion Tomato chutney recipe and after several recipes and experiments, I reformed this recipe, till I got the perfect taste. This recipe balances the acidic factor very well, making it more appealing and tasty. It is easy to prepare with simple ingredients.
