Firstly, wash the sabudana/sago and soak them for 5-6 hours in the water in a container.
The water level should be just 1 cm above the sabudana in the container.
Keep stirring the sabudana in the container every two hours to maintain uniformity.
After 5-6 hours, check them by hand, if still hard keep them soaked for a few hours more.
Once they are soft, strain the excess water and keep it aside.
Please Note: sabudana comes in different sizes and soaking time may differ.
Now mash the boiled potatoes with the help of a masher or your hand.
Take a big mixing bowl, add drained sabudana, mashed potatoes, finely chopped green chilis, fresh coriander, red chili powder, and sendha namak / rock salt.
Mix well all the ingredients.
After that, make flat patties or cutlets or tikkis from the mixture.
Heat enough oil in a Kadai and put 3-4 tikkis or cutlets in the Kadai in one go.
After that, fry it for a few seconds then gently flip it to fry the other side.
Fry it till it turns golden brown from both sides on medium heat.
Take out the sabudana cutlets on the kitchen paper napkin to absorb extra oil.
Similarly, prepare all Sabudana vadas.
Finally, hot, delicious, and crispy sabudana tikkis for fast are ready to be served.
Serve these sabudana cutlets for Navratri fast with green coriander chutney and Tamarind Chutney.
