Soak both the daals in water for five to six hours or overnight
Wash and drain the daals and ensure that all the grit has been removed
Mix the garlic, chillies, salt and coriander leaves with the daals and put through the blender.
Do not blend into a very fine paste; some of the daal should be only half crushed
Mix in the Eno
Shape the mixture into round balls, flatten slightlywith wet fingers, and deep fry in medium hot oil. Do not let them go crispy
Keep ready a pan of iced water. Remove the wada from the frier and put them into the water
Soak until the wadas are cold. Then squeeze gently with fingers to remove all the water and place in a serving dish 2-3 inches deep
Mix the sugar, salt (to taste), chaat masala, cumin seeds and green chillies into the yoghurt and whisk
Pour over the wadas and decorate with chilli powder, cumin seeds and chopped coriander leaves
