1 tablespoon per 1 tablespoon of cornstarchPotato starch has excellent thickening properties and gelatinizes at a similar temperature to cornstarch, allowing it to bind the egg mixture effectively without adding flavor. This helps maintain the structural integrity of the frittata.

Compared to cornstarch, potato starch yields a similarly tender and cohesive frittata, preserving the desired lightness and moisture balance.
