In a pan, mix all the ingredients to the gram flour. Whisk it to a smooth batter.
Pressure-cook the batter up to 3 whistles.
Wipe thoroughly both the inside and outside of 3-4 flat steel plates (thalis).
While the batter is hot, spread it thinly with your fingers, first on the inner surface of the plate and then on the outer surface of the plate. Repeat for rest of the plates. Let the batter cool.
Gently roll up the dry batter, like a swiss roll. Cut each roll into 1″ pieces. Arrange them in a serving plate.
