When to substitute vs when not to
Substitutions work best in forgiving recipes like muffins, quick breads, and cookies. They're riskier in precision-dependent recipes like macarons, choux pastry, or laminated doughs where the original ingredient's exact properties (fat content, water content, acidity) are critical to the chemistry.
