Ulundha Vadai/Methu vadai:
Ulundha Vadai is a very popular appetizer made in all occasions and seems deliciously appealing and ravenous to eat. Medhu Vadai normally has a crispy outer layer and spongy inner part, and this scrumptious taste which can not be explained through words.
It is just awesome to have and makes all of us happy in every situation.This is done easily with simple ingredients by all home makers, even though I feel like sharing some tricks and suggestions which I inherited from my mother, to prepare better vadai.

Ingredients:
Urud dal-1 cup
Toor dal-2 tsp,
Toor dal help us to reduce less absorption of oil.

Method to follow:
Wash 3 times and soak Urad dal,Toor dal and Raw Rice for 3 hours.
Drain Water and Grind with all other ingredients mentioned above until fluffy,Sprinkle water occasionally,add Salt before you transfer the batter to the Vessel.
To check perfect consistency drop little batter in a bowl of water,the batter floats on top like a ball as you drop, without any disperse of batter.
Refrigerate for 3o minutes, wet your hand and mix the batter by beating it well from the bottom this helps the Vada becomes more fluffy.
Add all chopped Ingredients and mix it once again.
Heat oil in a wide pan ,wet your hand take a small ball of batter, press it in the middle to make a hole, this helps to puff up and even distribution of heat to cook inside.
