All-Purpose Flour (Best Option)
1 cup all-purpose flour per 1 cup cake flourAll-purpose flour has a moderate protein content (around 10-12%) that is close enough to cake flour’s lower protein level to produce a tender coating without becoming tough. The protein content helps the flour absorb moisture and bind to ingredients, which is essential in stir-fry coatings.
To mimic cake flour more closely, you can sift the all-purpose flour to aerate it before use, which helps lighten the texture. Watch for slightly denser coatings and avoid over-mixing to prevent gluten development.
The final stir-fry coating will be slightly less delicate than with cake flour but still tender and crisp enough to complement the dish’s texture and flavor.
