Rabdi is a classic, traditional Indian sweet. A rich dessert that is a mixture of thickened creamy milk and bits of malai (top of milk) that is lightly sweetened with sugar and flavored with saffron and cardamom powder. The making of authentic rabri recipe is a laborious process that requires cooking full fat milk over a slow flame till it reduces to a thick mixture. The key to a rich and creamy Rabri lies in the quality of milk used and simmering the milk over low flame.
