Take the dough and divide into small equal sized portions.
Flatten the dough with fingers, put the filling portion and seal the dough as shown in the pic.
Similarly, fill and roll out all the portions of the dough. Keep all the kachoris covered.
Heat oil in a kadhai or heavy bottomed pan. To fry the kachoris the oil should be warm, not hot.
To check the correct temperature of oil, drop a small portion of dough into it should sizzle and rise slowly not immediately. The temperature of oil is very important as if the oil is very hot, kachori covering will cook from outside only and the inside will remain raw.
Drop 3-4 kachoris in oil and fry on slow flame. The secret to bubble free kachoris is frying on low flame.
Fry all the kachoris till light brown. Serve hot with kadhi and chutneys.
