Identify how the recipe uses matzo meal: coating (crisp texture) or binding (structure with moisture absorption).
Start with the listed ratio, using fine crumbs for coatings and starch/flour-style swaps for binding.
Adjust texture: if the mix seems too wet, add 1–2 tablespoon more crumbs/starch; if too dry, add 1–2 teaspoon water or egg to bind.
Rest 5 minutes before baking/frying so the crumbs absorb and set evenly.
Taste-check the texture at the first bite; for more crunch, choose finer crumbs or reduce moisture in the batter.
