Kalojam Sponge is a popular Bangladeshi dessert made from chhana (a type of fresh cheese), sugar, and water. It is often flavored with cardamom and saffron and then deep-fried in oil. After frying, it is soaked in sugar syrup, which gives it a sweet taste and a spongy texture. Kalojam Sponge is usually served during festive occasions and celebrations such as weddings, Eid, and other special events. It is similar to other South Asian sweets like Gulab Jamun but has its own unique flavor and texture.
