Soak sabudana (tapioca) in water overnight for 5-6 hours. When they have become soft, drain all the water using a colander.
1 Cup Sabudana (Sago/Tapioca Pearls)
Boil, peel and mash the potatoes. Add them to a large mixing container along with the sabudana.
2 Potatoes
Roast and coarsely grind the peanuts. Add these to the mixture as well.
1/2 Cup Peanuts
Add red chilli powder, cumin powder, coriander powder and salt.
1/2 Teaspoon Red Chilli Powder, 1/2 Teaspoon Coriander Powder (Dhaniya Powder), 1/2 Teaspoon Cumin Powder (Jeera Powder), 1 Teaspoon Rock Salt (Kala Namak)
Also add finely chopped green chillies, cumin seeds (jeera) and lemon juice.
1-2 Green Chillies, 1/2 Teaspoon Cumin Seeds (Jeera), 2 Teaspoon Lemon Juice
Mix all the ingredients well.
Divide them into small lemon sized portions and shape them into round flat patties.
Fry the patties in medium hot oil till they turn golden brown. Do not set the heat to a high setting, otherwise the vadas will not get cooked properly from the inside. Drain the excess oil on an absorbent paper.
Sabudana Vadas are ready. Serve them hot with coriander chutney, tamarind chutney or tomato ketchup.
