To a mixing bowl add flour, salt and oil. Add water as needed and make a smooth dough.
Knead it well to a soft dough. Wrap it in a moist cloth and keep it covered. You can also keep it in a bowl and cover. Allow to rest for 30 mins.
Divide the dough to 8 equal parts. Sprinkle the rolling area with little flour. Flatten a ball and sprinkle little flour over it.
Begin to roll it evenly to 6 to 7 inch round layer. Sprinkle ajwain or powder evenly all over. Roll the layer once more lightly.
Fold half of it. Repeat folding to make a triangle.
Roll this evenly to make about 8 inch paratha.
Heat a tawa over a medium high flame. While the tawa heats, you can roll the next paratha. When it is hot enough place the parantha on the tawa. Within few seconds you will see bubbles. Then flip it and cook on both the sides until it puffs and gets golden brown spots. Smear ghee all over.
If you are a novice cook, then roll and fry them in 2 batches. Roll 4 parathas and finish frying them. Then make the rest and fry.
Serve with a curry.
Stack ajwain paratha in a kitchen tissue or a cotton cloth to keep them soft.
