In a large mixing bowl, combine the atta and besan flours, ajwain, hing, cumin powder and turmeric powder. Add the oil and rub it into the flour mixture using your fingers until it resembles coarse crumbs.
Toss in the chopped methi leaves, onions, garlic, cilantro, ginger, and green chilies. Mix thoroughly to distribute the flavors evenly.
Gradually add small amounts of water while mixing until the dough starts to come together. Once it clumps into a rough ball, begin kneading.
Use your knuckles to flatten the dough, then gather it towards yourself using your palm and fingers.
Continue kneading with your knuckles for 5–6 minutes, flattening and gathering repeatedly.If the dough feels tight or dry, sprinkle a little water (but avoid over-wetting it).
In the final 1–2 minutes, add a teaspon of oil and knead to make a smooth and firm dough. It should not be too soft.
Cover the dough with a kitchen towel and let it rest for 15–20 minutes. During this time, it will soften further and be ready for rolling.If you are not planning to make parathas right away, place the dough into an air tight container with lid and refrigerate for 2-3 hours
