As I have had the pleasure of living for a good no of years in Karataka, I am including some popular cuisine from this state besides Kerala again influenced from my Palakkad based mom and a good many dishes from states of Gujarat and Maharashtra as I have spent some years in these states too.
This is a very popular dish from South Karnataka, Mangalore Udupi regions somewhat closer to our own Mor Kuzhambu from Tamil Nadu.,
Majjige Kayi Huli with any vegetables like pumpkin, ladies fingers, beans is prepared more or less the same way we prepare the mor kuzhambu.
Majjige means buttermilk in Kannada, huli is tamrind and kayi means coconut.
This is a mildly spiced , coconut based dish made with green chillies and pinch of tamrind in the authentic version.
