โญ Potato Starch (Best Fat-Free Option)
1:1 (1 tablespoon potato starch per 1 tablespoon cornstarch)Potato starch is a fine powder that gelatinizes at a slightly lower temperature than cornstarch, providing excellent thickening and moisture retention in meat mixtures. It forms a gel that helps bind the meatloaf ingredients together, preventing crumbling.
When using potato starch, mix it thoroughly with the wet ingredients to avoid clumping. It is best added towards the end of mixing to preserve its thickening power. Avoid overheating as it can break down under very high heat but typical meatloaf baking temperatures are safe.
Compared to cornstarch, potato starch yields a similarly moist and tender meatloaf with a slightly softer crumb, making it an excellent direct substitute without impacting flavor or texture negatively.
