Mix semolina, salt and enough water to knead dough. Knead dough with your hands to a soft dough. Set aside covered with a wet cloth for about 15-20 minutes.
Take a fist sized lump of dough and make a ball. With the help of some dry flour or semolina, roll into big thin rounds. Cut small puris from it with the cutter. Approximately (1 ½") diameter. (You may use a sharp edged lid of a bottle, if the size is alright.) Remove the frills formed and mix into remaining dough.
Heat oil in a pan and deep fry the puris until they are very light brown and crisp. Keep the puris covered with a moist muslin cloth if there is a delay in frying. Drain and rest in a colander or over kitchen paper for a while for the oil to dry out. Store in an airtight container when cool.
