Dahi Bhalla

Dahi Bhalla (also known as thayir
vadai in Tamil and perugu
vada in Telugu, mosaru vade
in Kannada, ଦହି ବରା Dahi Bara in Oriya and Doi Bora
in Bengali) is an Indian chaat, prepared by soaking bhallas in thick sweetened
yogurt (dahi) along with fennel flavoured
tamarind chutney and mint chutneys

The bhall is a shape of dumpling made of paste with
soaked dal lentils mixture. The individual vadas are then shaped and deep-fried. Although battered and deep-fried, the finished product is  not oily  since steam build-up within the vada pushes all
oil away from within the vada hence it does not soak oil.
