Boil sweet potatoes in a pressure cooker until firm.

Smash the boiled sweet potatoes using your hands or a ladle.

In a big bowl, add wheat flour, mashed sweet potato, salt, red chilli powder, ajwain, and jeera seeds.

Mix everything together thoroughly.

Add water little by little and make a soft dough.

Cover the dough with a cotton cloth and let it rest for 10 minutes.

Using a chapati roller, make a round shape roti or chapati.

Heat a pan and flip the roti on both sides.

Drizzle a little oil on both sides to get a mild golden color.

Cook until done.

Switch off the stove and serve hot.
