Heat the milk in a saucepan over medium heat till it comes to a boil.
Take the pan off the heat.
Add 2-3 tbsp of lemon juice and mix gently. Allow the milk to rest for 2-3 minutes.
Put the pan back on medium heat. The milk will begin to curdle.
When you see the whey or the greenish liquid, take the pan off the heat.
Gently stir the mixture with a spoon or spatula. Curdled milk will gather up into lumps.
Drape a colander with a cheesecloth.
Pour the curdled milk mixture into the cheesecloth.
Wash the paneer or chenna under running cold water. This stops the paneer from cooking further and also removes the lemon juice or vinegar.
Gather the ends of the cloth and squeeze the chenna gently to remove excess water.
Place the chenna with the cheesecloth in the colander again. Cover the chenna with the cloth.
Put a small flat lid or plate on top of the bundle of covered chenna. Place a brick or something heavy over it. This helps to remove the excess water faster.
Leave for about 30 minutes.
Preparation of the Chenna/ Paneer Balls:
Remove the chenna from the cheesecloth into a big bowl or tray.
Knead the chenna using the heel of yoru palm till its soft smooth and it no longer sticky. This takes about 5-10 minutes.
Divide the chenna into 12 -14 parts.
Roll each part into a ball that is completely smooth without any cracks.
Preparation of Rasgulla:
Take a big wide pan with a lid.
Add water, sugar, cardamom and saffron.
Place the pan over medium heat and bring the water to a rolling boil.
Add the chenna balls gently to the boiling sugar water.
Allow the chenna balls to boil for 20 minutes.
Switch the heat off after 20 minutes. Don't be tempted to open the lid as the ragullas may deflate.
Allow the ragullas to cool down in the syrup without opening the lid for at 30 minutes to 2 hours.
For chilled rasgulla, put in the fridge with the syrup for about 30- 60 minutes.
Serve Kesar Rasgulla with a little syrup drizzled over it.
Notes
Make sure the chenna mixture is smooth and not sticky after kneading it.
Don't use less water otherwise the syrup will become thick and the rasgulla will not cook properly.
If you don't have lemon or vinegar to curdle the milk use ¼ cup plain yogurt.
