To make it more flavorful, add chopped cilantro, ginger-garlic paste, green chillies, and fresh greens like methi or spinach to the boiling water. You can also add spices like cumin seeds, Kasoori methi, turmeric powder, coriander powder, cumin powder, garlic powder, onion powder, dried herbs, and garam masala to the water. Crumbed paneer, chopped onions, or mashed potato can also be mixed into the dough. To make fluffier roti, add a teaspoon of baking powder and baking soda. This will make the rotis stay softer for longer.
