Pour your oil into a deep saucepan or wok. Place on a low to medium heat. You want your oil to be very warm but not very hot (you don't want to see a sizzle when you place the Gulab Jamun into the oil, you want them to cook slowly)
Once the oil has reached the right temperature (you can tell by placing a chopstick into the oil. If bubbles slowly start to form around the chopstick, then the oil is ready), add in the Gulab Jamun. (Check out my video on Instagram if you're struggling).
Stir continuously and cook for around 3-5 minutes or until the dumplings have grown in size and are golden brown.
Remove the dumplings and add straight into the syrup mixture (make sure the syrup has cooled down).
Place the lid on the saucepan and leave the Gulab Jamun for 2 hours to soak up the juices.
