โญ All-Purpose Flour with Cornstarch (Best Nut-Free Option)
1 tablespoon all-purpose flour + 2 teaspoons cornstarch per 1 tablespoon cake flourCake flour is low in protein (about 7-8%) which contributes to a tender texture. By mixing all-purpose flour (higher protein) with cornstarch (no protein), the overall protein content is lowered, mimicking cake flour's properties. This balance helps the omelette remain soft and delicate rather than rubbery or dense.
To ensure success, sift the mixture before use to incorporate air and prevent clumping. Avoid overmixing the batter to maintain tenderness.
Compared to using cake flour directly, this substitute produces a very similar texture and mouthfeel, maintaining the lightness and slight fluffiness expected in an omelette.
