You can add 1 tsp ghee or oil while kneading for softer rotis.
Ensure the dough is soft, or the edges may break while rolling.
If the dough mixture is too warm to knead, use a masher or steel tumbler to smooth it out, then knead.
Keep the dough balls covered with a wet towel to prevent drying out.
Keep cooked rotis covered in a container until serving.
