soak one cup of urad dal with enough water.
soak for 3 - 4 hours. soaking for more than 4 hours makes the batter watery and absorbs oil.
grind to fine fluffy paste adding water as required. i have added 4 tbsp of water to make smooth thick paste.
transfer the urad dal paste / batter to a large mixing bowl.
beat and mix the batter in circular motion till they turn light. this helps to incorporate air into batter and make vadas soft and fluffy.
now add a tsp of rice flour and salt to taste. adding rice flour makes vadas crispy.
to test the consistency of batter drop a small ball of batter into bowl containing water. if the ball floats up then the consistency is rite.
add chopped ginger and green chilli.
also add in chopped onions and coriander leaves.
now add finely chopped spinach / palak leaves.
mix the batter well.
heat the oil in large kadai. wet your hands with enough water and take a small ball sized batter and make it round.
now slowly shape the edges and make a hole at the centre like you prepared in bread vada.
deep fry the palak vadas slowly on medium flame.
fry on both sides till they turn golden brown.
drain on paper towel to remove excess oil.
serve hot vada with chutney or sambar of your choice.
