In a mixer jar, add 1 cup of sabudana and grind it into a fine powder.
Transfer the ground powder into a mixing bowl. Then add 2 medium-sized boiled potatoes (about 1 cup) and salt. Mix well.
Gradually add water and knead the mixture into a soft dough (refer to video for guidance).
Cover the dough and let it rest for 10 minutes.
Take a small portion of the dough and roll it into a smooth ball, then flatten it to make a disc.
Sprinkle some dry farali flour and roll the disc into a medium-sized circle.
Heat a tawa on medium heat. Once hot, place the rolled roti on the tawa and cook it on medium flame. Repeat the process for the remaining dough.
Place the cooked rotis in an insulated container.
Serve the farali sabudana roti with batata chips nu shaak.
