Ingredients

Oil: Used for both sauteing the base ingredients and tempering, oil helps in releasing and blending the flavors beautifully. It also adds a slight richness to the chutney’s texture.

Onion: Sliced onions bring natural sweetness and depth to the chutney. When sautéed, they mellow down and balance the tang of the tomatoes.

Tomatoes: Tomatoes are the heart of this chutney, providing a vibrant color and tangy base. They add juiciness and a fresh flavor that defines the dish.

Green Chillies: Slit green chillies bring heat and a bold punch to the chutney. They’re sautéed to mellow the sharpness and blend into the flavor.

Garlic: Garlic adds a strong, earthy aroma and taste that enriches the chutney. It complements both the spices and the vegetables.

Coriander Leaves: Chopped coriander leaves add a refreshing, herbal note. They brighten up the chutney with color and flavor.

For Tempering - Mustard seeds, urad dal, cumin seeds, chana dal, asafoetida and curry leaves is used.

Hacks

Use Shallots Instead of Onions: If you have pearl onions or shallots, use them for a sweeter, more traditional taste often found in Tamil Nadu-style chutneys.

Use Leftover Chutney Creatively: Leftover chutney makes a great base for sandwiches, spreads for wraps, or even mixed into rice for a quick tomato rice dish.

Roast Ingredients for Extra Flavor: Roasting the onions and tomatoes a little longer until they slightly caramelize adds a deep, smoky flavor to the chutney.

Make a Big Batch and Store It: This chutney (since it’s coconut-free) can last up to 5 days in the fridge. Make a large batch and use it throughout the week.

Expert tips

Saute Until Soft and Aromatic: Cook the onions and tomatoes until they are completely soft and slightly caramelized, this enhances sweetness and depth of flavor.

Use Ripe Tomatoes: Always use well-ripened tomatoes for a naturally tangy and juicy chutney. Avoid unripe ones as they can make the chutney sour or bland.

Let It Cool Before Blending: Allow the sauteed mixture to cool slightly before grinding. This prevents steam buildup and helps preserve the taste and texture.

Use a Heavy-Bottomed Pan: Cooking in a heavy-bottomed kadai or pan ensures even sauteing and prevents the ingredients from burning.

Tempering: For Tempering spices, use gingelly oil also known as Indian sesame oil for best flavour.
