Rinse 1 cup of sabudana well until the water runs clear.
Soak it in ¾ cup of water overnight or for 4-6 hours.
After soaking, the sabudana should have absorbed all the water. It should be soft—press it with a finger to check if it crushes easily.
In a mixing bowl, add soaked sabudana, 1 cup grated potatoes, ½ cup peanut powder, 2 tbsp green chili paste, salt to taste, 1 tsp lemon juice, ½ cup coriander leaves, 1 tsp cumin seeds, and a pinch of Kashmiri red chili powder. Mix well.
Ensure the vada mixture is properly bound together (refer to the video).
Take some mixture and shape it into a round patty.
Heat oil in a pan, then add the vadas one by one and fry them on medium heat until they turn golden brown and crispy on both sides.
Drain the fried vadas on a wire rack. Repeat the frying process for all the vadas in the same way.
Serve the sabudana vada with farali kadhi.
