Onion Chutney For Idli Dosa | Vengaya Chutney

Onion Chutney For Idli Dosa | Vengaya Chutney

The Tamil word for onion is vengayam. So this chutney is also called as vengaya chutney.

Onion chutney has amazing flavours – the sweetness of the onions, the smoky flavour of the red chilies, sourness of the tamarind and the earthy flavor of the lentils.

Onion chutney goes well with idli, dosa, adai, rice, upma, bread and even rotis.

The type of red chilies used will decide the colour of the chutney. If you use kashmiri red chilies the chutney will be red in colour. I prefer to use a few spicy guntur chilies and a few byadgi red chilies as I do not want the chutney to be red, but want it to retain the pinkish hue of the onions.
