Rosogolla is a famous Bengali sweet that originated in Kolkata. It is made by kneading cottage cheese (chhena) into small balls, which are then cooked in a sugar syrup until they become soft and spongy. The syrup is flavored with cardamom or rose water, giving the rosogollas a delightful aroma. They are often served chilled and are a popular dessert option during festivals and special occasions. Rosogollas are loved by people of all ages and are a must-try when in Kolkata.
