Set oil or ghee for deep frying to heat up in a deep cooking pot. Make sure that the oil quantity is enough so that the gulab jamuns remain fully submerged while deep frying.
Once the oil is heated up, to check the oil temperature, add a small piece of dough to the hot oil. It should rise up quickly without sizzling. If you use a candy thermometer, heat the oil (or ghee ) to around 350-365°F.
Carefully, add the rolled jamun balls into the hot oil. Do not over crowd.
While frying, maintain a consistent oil temperature and gently turn around the jamuns to ensure even cooking. It should take about 5-7 minutes per batch. You might see some foaming in oil due to baking soda.
Once browned,using a slotted spoon remove all the excess oil and place the fried balls on paper towels for 10-15 seconds.

While they are still warm, place the fried gulab jamun in the warm sugar syrup.Finish deep frying all gulab jamun and soak in syrup immediately.
Once you've added all the gulab jamun to the syrup, place the pot on a low flame for 1-2 minutes. Warming the syrup helps in better soaking. Take care not to let boil, else gulab jamuns will burst. Cover the pot and let stand undisturbed for at least 30-45 minutes.
