What You Need to Know
Lecithin (phosphatidylcholine) reduces surface tension to create stable bubbles in low-pH liquids through hydrophobic/hydrophilic interactions, without requiring whipping agents like proteins.
Provides bright acidity as edible garnish without liquid runoff, allowing precise placement on heat-sensitive dishes.
