What You Need to Know
Early acid introduction lowers interfacial tension between phases by protonating hydroxyl groups on polyphenols (particularly quercetin glycosides in parsley), creating nucleation sites for oil droplet formation during shear.
Prevents vinaigrette-style separation in herb sauces, allowing thicker texture without gums or starches.
