Firstly, in a sauce pan, add sugar, water and bring it to a boil.
Into it add cardamom powder and boil the syrup on medium flame until it turns sticky/syrupy.
Rest it aside once the syrup is done.
For the gulab jamuns using bread:
Take the bread slices, remove its corners.
Blend the white part to make bread crumbs.
Into the bread crumbs add milk gradually and knead it to make a dough.
Take small portions of the dough and make round balls.
Take a wok, add oil for deep frying and heat the oil.
Drop the gulab jamuns into it and deep fry them until they turn golden brown.
Take the gulab jamuns out and immediately dip them into the sugar syrup.
Cook the dipped gulab jamuns for a minute or two/ rest the balls into the syrup until they absorb the syrup.
They are ready to be served immediately or they can be stored in refrigerator for a while before having them.
Here I have made bread crumbs and made the dough by adding milk and kneading but instead of doing that another easy way would be to dip the bread into milk, squeezing it and making a round ball and frying them and dipping into the syrup.
