Peel and cut the purple sweet potato into chunks. Steam or boil for 12-15 minutes, until very tender. Drain well and mash until smooth, then let it cool until just warm.

In a bowl, combine 1 cup packed mashed sweet potato with the flour, flaxseed, salt, cumin seeds, and oil. Add warm water a tablespoon at a time until a soft dough comes together.
03 -
Knead the dough for 3-4 minutes on a lightly floured surface. Cover with a towel and rest for 15 minutes so the flour hydrates.
04 -
Divide the dough into 8 equal balls. Roll each ball into a thin 6-inch round, dusting lightly with flour only as needed to prevent sticking.

Heat a dry tawa, griddle, or cast iron skillet over medium-high heat. Cook one roti for 40-60 seconds, flip, and cook the second side for 40-60 seconds until brown spots appear.

Transfer each cooked roti to a clean towel and keep covered while cooking the rest. Brush lightly with oil if desired and serve warm.
