Identify your recipe: fried (batter/dough), baked (cakes/pastries), or thick thickening (coating/roux).
Choose the closest match from the list: use the 1:1 options first for the least change.
Measure by weight when possible; for cake flour, use the listed reduced ratio to avoid crumbly dough.
Adjust hydration gradually: if the dough feels tight, add a few teaspoons of water (or milk) and rest 5 minutes.
Test texture before committing—make a 1-2 bite trial (fry or bake) and refine with 1-2 tablespoons flour or water.
