Notes
What's the difference between medhu vada and Mysore bonda?
Medhu vada and Mysore bonda are more or less similar, the only difference is the addition of fresh or dessicated coconut in the Mysore bonda. The second difference is the shape of medhu vada is like a donut but mysore bonda is round ball-shaped.
I saw recipes where Mysore donda is made with plain flour and yogurt? Which recipe is authentic?
As far as authenticity is concerned, I am not the right person to answer that. I too have seen recipes where Mysore vada is made with plain flour and yogurt. So after a lot of research and talking to some of my friends from Karnataka state I got to know that the bonda made with urad dal is Mysore bonda and the one made with plain flour and yogurt is Mangalore bonda.
Can we store the bonda batter?
It is advisable that you make the fresh batter to make Mysore bonda but if required you can store the ground urad dal paste in the refrigerator for 1-2 days. Once ready to make add the rest of the ingredients and make the bonda. Store the leftover bonda at room temperature or in the refrigerator for a couple of days.
How to make the fluffy and yet crispy outside bonda?
To make the bonda crispy outside and fluffy and soft from inside make sure the batter is smooth. Try not to add too much water while grinding and the batter should be a thick paste.Oil should be medium hot while frying the Mysore bonda.
