Bring water and sugar to a rolling boil in a deep pot. Stir to dissolve the sugar. When the water is boiling carefully slip chenna balls in the water and cover the pot. Allow them to boil on medium-high for 5 minutes. Now open the lid and stir once with a skewer without touching the balls.
6 Cups Water, 1 Cup Sugar
Make sure there is ample of space in the pot for the chenna balls to roll freely without touching each other. Sometimes I cook them in two batches to make sure they don't touch each other as they boil vigorously in water.
After 5 minutes, turn the heat to medium, but make sure water is boiling at all the times. This reduced heat will allow the chenna balls to cook from the inside. Cook for another 10 minutes and remove the pot from heat.
Without opening the lid, allow the water to come to room temperature. That way rasgullas will hold their shape beautifully. The balls will have doubled in size and will sink to the bottom of pot.
If you'd like your rasgullas on the sweeter side, add upto 1 more cup of sugar and utilize 1 cup of water in which you boiled chenna balls. Mix that water with sugar in a medium pot and bring it to a boil. Stir sugar completely in it, turn it off and allow to cool.
Add cooked rasgullas in this cooled syrup and stir using the handle of pan. Add rose water in too. Garnish with slivered pistachios and serve chilled.
½ teaspoon Rose Water, Few Slivered Pistachios
