Grating carrots for gajar ka halwa increases the surface area, allowing them to cook quickly and evenly, resulting in a smoother, more consistent texture and enhanced flavor absorption.
When making gajar ka halwa, the carrots need to cook down until they are soft and almost melt into the milk and sugar. Grating the carrots achieves this much faster than using chopped or sliced carrots. The increased surface area allows the carrots to release their moisture more readily, which helps them cook faster and more evenly. This also allows the carrots to better absorb the flavors of the milk, sugar, cardamom, and other spices used in the recipe. The result is a halwa with a smooth, almost creamy texture, where the individual strands of carrot are no longer distinct but rather blend seamlessly into the dessert. Using grated carrots ensures that the halwa cooks properly and achieves the desired consistency and flavor profile.
Use a food processor with a grating attachment for faster and more consistent grating, but be careful not to over-process the carrots into a puree. You want distinct shreds, not a paste.
