A famous evening snack of the Kannadigas of Bengaluru and surrounding regions is the "Heerekai Bonda" or Ridge Gourd fritters.
No matter what the occasion, this is one snack /side dish which will always be made.
On festivals like Ugadi and Sankranti this bonda is served as a side dish with Bisibelebath.
This "Heerekai Bonda" is also one of the snacks served during most tea parties along with "Kesaribath" and "Kharabath".
Infact this used to be the standard menu for tea parties in the 70s and 80s.
Easy to make but yes a bit of an indulgence since this involves deep frying.
However, my practice is to use as little oil as possible and fry one or two bondas at a time and then drain on paper towels, and also discard the oil after use.
A good snack on a rainy monsoon evening too.
