All-Purpose Flour (Best Option)
1:1 by volumeAll-Purpose Flour contains moderate protein content, which allows it to thicken and bind ingredients in a marinade effectively, similar to bread flour. The starches gelatinize upon mixing, helping the marinade cling to proteins or vegetables.
For best results, whisk the flour thoroughly into the marinade to avoid lumps and allow a brief resting period for full hydration. Avoid overheating to prevent a pasty texture.
Compared to bread flour, the marinade may be slightly less elastic but will retain a smooth consistency and proper adherence to the food.
