Place the ginger, garlic, and green chilies in a mortar and grind them into a smooth paste using the pestle.
In a large mixing bowl, add the sifted makki atta.
Add the grated radish, ginger-garlic-chili paste, crushed kasuri methi (dry fenugreek leaves), salt, and turmeric powder to the bowl. Tip - Before adding the radish,taste the radish to make sure that they are not bitter else taste of your roti will be spoiled.
Using your hands, mix the ingredients thoroughly into the makki atta.As soon as the salt and radish come into contact, the radish will begin releasing its water, which the flour will start absorbing.
Gradually start adding warm water, a little at a time, and mixing it with the flour.
Now you will have to go by how atta feels - add little water slowly as needed and bring the flour together. Keep in mind that the radish will still continue to release its moisture so the dough will get softer as it sits.
Once there is no dry flour remaining, start smoothening the dough using the palm of your hand as you knead. This a bit tedious step and could take 6-8 minutes. You will yield a soft dough. The dough should not be sticky.
Set aside the dough for 15-20 minutes. Not needed but I have a habit of resting any sort of dough so I do the same here.
