This technique works primarily through phase_stabilization. Key molecules involved include lecithin, proteins, surfactants. The process creates flavor compounds through phase_stabilization.

Heat butter until melted, then cook over low heat until milk solids settle. Skim foam, pour clear butter into a clean container. Target: 40–45°C. Use immediately while warm.
Bring fond (stock or broth) to room temperature or slightly chilled. Cold liquid prevents premature coagulation of egg proteins. Target: 15–20°C.
Immersion blender and vessel must be completely dry. Any water causes instantaneous breakage. Wipe vessel with a clean towel.
Pour cold fond into the tall cylindrical vessel. Add a small amount of binding agent (egg yolk or starch slurry). Submerge the immersion blender to the bottom.
Begin adding clarified butter in a thin, steady stream while the blender runs at medium speed. Keep the blender tip at the bottom for the first 30 seconds to establish the vortex.
Once the base is thick and glossy, slowly raise the blender while continuing to blend. This distributes the oil evenly throughout the sauce volume.
Check sauce temperature with a probe thermometer. Between 45–55°C is the safe window for hollandaise-style emulsions. Above 55°C, egg proteins begin to coagulate.
Season with salt, a few drops of lemon juice, and optional white pepper. Blend briefly to incorporate. Hold in a bain-marie at 60–65°C. Do not cover.
