Nolen gur rasogolla, also known as date palm jaggery rasgulla, is a traditional Bengali sweet made with chenna (cottage cheese) balls cooked in a syrup made with date palm jaggery. It has a soft and spongy texture with a unique caramel-like flavor from the jaggery. The chenna balls are cooked in the jaggery syrup until they become light and spongy. Nolen gur rasogolla is a delightful dessert that is often enjoyed during winter months when date palm jaggery is available.
