Step-by-Step Tutorial
PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Heat-controlled aeration and protein denaturation creating a stable foam matrix.
Origin: French (17th century) — Western Europe
See full technique reference →Lecithin-mediated emulsion stabilized by partially denatured yolk proteins (livetins, phosvitins) through controlled heat exposure (60-65°C), with subsequent fat incorporation via laminar flow whisking.
Foundational technique for emulsified sauces requiring precise temperature control to balance structural integrity with silky texture.
Temperature
63°C
58°C - 68°C
Time
5 minutes
3 minutes - 8 minutes
Equipment
Hollandaise (Normandy): Creates stable emulsion matrix for butterfat incorporation
Choron sauce (Paris): Provides heat-stable base for tomato concassé addition
Primary Reaction
Protein denaturation and phospholipid reorganization
Key Variables
Graininess
Cause: Over-aggregated proteins from >70°C exposure
Fix: Immediate ice bath shock + strain
Breakage
Cause: Insufficient lecithin hydration time
Fix: Re-emulsify with 5ml cold water
