Grind peeled ginger, garlic, red chillies with enough water, until smooth.
In a mixing bowl, mix flour, salt and ajwain and pour this ground chilli mix. Add 1 tablespoon oil and enough water to mix to a stiff dough. Keep aside for 15 mins.
Again knead the dough after setting time and divide to equal balls. Rest it for 10 mins.
Roll into thin chapati and cut first into strips and then diagonally to make diamonds using a knife/pizza cutter.
Use a thin spatula to take out the diamond cuts from the rolling board. Don't worry if it gets together. When you drop in oil, it will separate. But be gentle when you gather, while dropping.
Deep fry in hot oil with medium flame and keep turning constantly for even cooking. When it is golden in colour and the bubbles and sounds ceases, drain it in paper towel.
