Notes
Slit green chilli can be added raw or into the tadka/oggarane.
Steamed corn kernels can also be added to kosambari.
Pomegranate can also be added for a sweet juicy bite.
Kosambari is best eaten fresh. Refrigerate leftovers as the fresh coconut in it can go bad if left at room temperature for long hours, especially in warmer climates.
