⭐ Potato Starch (Best Fat-Free Option)
1 teaspoon per 1 tablespoon of arrowroot powderPotato starch is a fine, neutral-tasting starch that gelatinizes at a similar temperature to arrowroot, making it an excellent thickener for egg-based dishes like omelettes. It helps bind moisture and provides structure without heaviness.
When using potato starch, mix it well with a small amount of cold water before adding to the eggs to prevent clumping. Avoid overheating as it can break down and lose thickening power.
Compared to arrowroot, potato starch produces a similarly tender and moist omelette, with a slightly more robust binding effect, which can be beneficial in maintaining shape during cooking.
