All-Purpose Flour with Cornstarch (Best Option)
1 cup all-purpose flour minus 2 tablespoons, plus 2 tablespoons cornstarchCake flour is low in protein and high in starch, which contributes to a tender, light texture. By removing 2 tablespoons of all-purpose flour and replacing it with cornstarch, you reduce the protein content and increase starch, closely mimicking cake flour's properties. This prevents the marinade from becoming too thick or gummy.
For best results, sift the mixture before adding to the marinade to ensure even distribution. Avoid overcooking the marinade after adding this substitute to prevent thickening too much.
Compared to cake flour, this substitute maintains a similar lightness and smoothness in the marinade, preserving its ability to coat and tenderize ingredients effectively.
