Identify your recipe goal: thickening (sauces), binding (batter/dough), or baking structure (cakes/breads).
Use the closest match from the table: starches for thickening/chew, flours for baked structure.
Measure using the listed ratio; if switching from cassava flour to a starch, start with the lower end when thickening sauces.
Test texture: simmer/thicken 30–60 seconds longer for starches if it looks thin, or loosen with a splash of water/broth.
For baking, add a binder if your batter looks sandy (xanthan gum, psyllium, or an egg) and re-test once.
