Garlic - you can use peeled garlic cloves which adds a slight garlic flavour to the chutney.

Dry Red Chillies - depending on the spice level, you can increase or reduce the dry red chillies.

Tamarind - a small amount of tamarind is added to balance the taste of the chutney.

Tempering - for tempering, I like to use gingelly oil which is Indian sesame oil along with mustard seeds, urad dal, dry red chillies, curry leaves.
