Achieve creamy, non-icy Kulfi by simmering the milk mixture for a long time to reduce water content and adding a thickening agent like cornstarch or breadcrumbs. Stir frequently during freezing to break up ice crystals.
The key to a creamy Kulfi lies in minimizing ice crystal formation. Here's a step-by-step guide:
Start with Full-Fat Milk: Use whole milk for a richer, creamier base. The higher fat content helps prevent ice crystals.
Simmer and Reduce: In a heavy-bottomed pan, simmer the milk over low heat. This process reduces the water content, concentrating the milk solids and fat, which contributes to a smoother texture. Aim to reduce the milk to about half its original volume. Stir frequently to prevent scorching.
Add Sweeteners and Flavorings: Incorporate sugar, cardamom, saffron, or any other desired flavorings. Ensure the sugar is fully dissolved.
Incorporate a Thickening Agent (Optional): A small amount of cornstarch slurry (cornstarch mixed with cold milk) or breadcrumbs can further enhance the creaminess. Add it gradually while stirring constantly to avoid lumps. Cook for a few more minutes until the mixture thickens slightly.
Cool Completely: Allow the mixture to cool down to room temperature, then chill it in the refrigerator for at least 4-6 hours, or preferably overnight.
Pour into Molds: Pour the chilled mixture into Kulfi molds or small disposable cups.
Initial Freeze and Stir: Freeze for about 2-3 hours, or until the edges start to set. Then, take the molds out and stir the mixture thoroughly with a spoon or fork. This helps break up any ice crystals that have formed.
Insert Sticks and Freeze Solid: Insert Kulfi sticks into the center of each mold and freeze for at least 6-8 hours, or preferably overnight, until completely solid.
Unmold and Serve: To unmold, dip the molds briefly in warm water or roll them between your palms to loosen the Kulfi. Serve immediately.
Don't over-sweeten the Kulfi mixture. Freezing tends to dull the perception of sweetness, so a slightly less sweet mixture will taste just right after freezing.
