Wash & soak sabudana in ¾ cup water for 6-8 hours or overnight. After the soaking hours, the sabudana will soak up all the water and fluff up. See note 1.
¾ cup sabudana or sago pearls, ¾ cup water
Take soaked sabudana in a large bowl, add rest of the ingredients except oil & mix well.
1 cup + 2 tablespoons boiled & mashed potatoes, ½ cup roasted peanuts, 1 green chilly, 2 tablespoons finely chopped coriander, ½ teaspoon cumin seeds, Juice of ½ lemon, ½ - ¾ teaspoon salt, ¼ teaspoon sugar, 15 curry leaves
Preheat the airfryer at 190C.
Grease your palm with oil, take a golf sized sabudana mixture on your palm and flatten it to form round discs or vadas. Repeat till all vadas are formed.
3 teaspoons cooking oil
Brush the airfryer mesh with oil, place vadas and brush some oil over the vadas. Avoid overcrowding and make sure that there is some gap between the vadas.
Airfry the vadas for 8 minutes at 190C, flip them once, brush with oil and air fry them at 200 C for 9 more minutes. They turn crisp once they cool down.
Repeat the same process for all the remaining vadas.
