โญ Cornstarch (Best Fat-Free Option)
1 tablespoon cornstarch per 2 tablespoons all-purpose flourCornstarch is a pure starch with high thickening power, making it an excellent substitute for flour in custard-like desserts such as panna cotta. It gelatinizes at a lower temperature and creates a clear, smooth gel that complements the creamy base.
When using cornstarch, it is best to dissolve it in a small amount of cold liquid before adding to the warm cream mixture to prevent clumping. Avoid overheating after thickening to maintain a tender texture.
Compared to flour, cornstarch produces a more translucent and silkier panna cotta with a cleaner mouthfeel, preserving the dessert's signature delicate consistency.
