Prepare the Khichu dough.

Preheat a steamer with water.

In a separate pan, heat water with ajwain, cumin seeds, salt, ginger, and green chilies.

Bring the water to a rolling boil.

Quickly add rice flour to the boiling water, scattering it evenly.

Do not stir. Allow the water to moisten the rice flour.

Using a wooden ladle, vigorously stir the mixture for a minute.

Remove the Khichu from the heat and pour it into a bowl.

When cool enough to handle, pinch the dough into 12 equal-sized balls.

Make an indent in the center of each ball, forming a doughnut shape.

Transfer the Khichu donuts to the steamer.

Steam for 5-7 minutes.

Remove the Khichu from the steamer and serve hot.
