⭐ Cornstarch (Best Gluten-Free Option)
1/2 the amount by volume (e.g., 1/2 tablespoon cornstarch per 1 tablespoon bread flour)Cornstarch is a pure starch that gelatinizes at lower temperatures and provides strong thickening power, making it efficient in salad dressings. It forms a clear, smooth gel that enhances the dressing’s viscosity without gluten.
To use cornstarch, mix it with a small amount of cold liquid before adding to the dressing to prevent clumping. Avoid overheating to prevent breakdown and thinning.
While it thickens more effectively than bread flour, cornstarch can give a slightly different mouthfeel—more slippery and less elastic—but this is generally desirable in dressings for a clean texture.
