• Wash the Sabudana/sago under running water 2-3 times. Discard the excess water and leave it covered, to soak overnight.
• In between if you feel the soaked sabudana looks dry then just add few splashes of water, keep it covered until you are ready with other ingredients.
• Meanwhile coarsely crush roasted peanuts in mortar pestle or just pulse into mixer. No need to make a fine powder.
• After that mash the boiled potatoes. Add  cumin, rock salt, sugar, minced green chillies, coriander leaves and lemon juice. To this add peanuts and soaked sabudana.
• Mix everything together to make a dough. Pinch a lemon size dough and shape it round. Flatten it with your palms, smoothen the edges.
• Don’t flatten them completely, keep them a little plump. This will make the vadas crisp from outside with a soft texture from inside.
• Repeat the process, make all vadas and store in an airtight container. Place this in the fridge until you air fry them.

To Air fry

• Preheat the air fryer at 200 degrees for 10 minutes. Brush a little oil on the Air fryer basket.
• Arrange prepared vada in a line leaving a little space between each of them. Brush oil over vada and Air fry for 10 minutes at 200°C.
• After that pull out the Air fryer basket, turn vadas upside down. Brush some oil on top. Air fry for 10 to 12 minutes until crisp at 200°C.
• Repeat the process for all the remaining vadas. Yummy, crispy, Air fryer Sabudana vadas are ready to devour.
