Sabudana should be washed and soaked in water for 2 hours.
In a few hours, you'll see that the sabudana pearl's size has grown.
Put them in a strainer, squeeze out extra water, and set them aside.
Boil 2 potatoes, peel and grate them and keep it aside.
To a bowl add ½ cup sabudana, 4 tbsp roasted peanuts, 1 finely chopped green chilli, ½ tsp grated ginger, 2 tbsp finely chopped coriander leaves, ¼ tsp turmeric powder, ¼ tsp garam masala, ½ tsp salt and mix well.
Make equal sized balls and flatten them to form a pattoe.
If the mixture is sticky, lightly oil your hands to prevent sticking.
For deep frying, warm the oil in a frying pan over medium heat. Slide 3–4 patties into it slowly when it is medium-hot.
Flip them over when top surface starts to turn light brown, and deep fried until both sides are golden brown.
Sago vada is ready; drain them and place them on a plate.

Serve the hot sabudana vadas with curd, a fiery green chutney, and tamarind chutney.
