Glossary Term: Hollandaise Sauce

Hollandaise Sauce Definition:

Hollandaise sauce is one of the five French mother sauces, made by emulsifying egg yolks with clarified butter and acid, usually lemon juice or vinegar. It is renowned for its silky, rich texture and bright, tangy flavor, often used to complement vegetables, eggs, or fish. The sauce requires careful temperature control to prevent curdling while achieving a smooth, stable emulsion. Hollandaise sauce is both a classical culinary staple and a technical benchmark for chefs and students.

Hollandaise Sauce Key Concepts:

Emulsification: Combines fat (butter) with egg yolks and acid into a stable, creamy sauce.
Temperature Sensitivity: Must be prepared over gentle heat; too hot scrambles eggs, too cold prevents emulsification.
Mother Sauce Role: Serves as the base for derivatives like Béarnaise or Mousseline sauce.
Flavor Balance: Acidity cuts the richness of butter, while egg yolks provide body.
Serving Context: Best made fresh and served warm, as it does not reheat or hold well.

What It Is Not

Not a mayonnaise, both are emulsions, but mayonnaise is cold and oil-based, while hollandaise sauce is warm and butter-based.
Hollandaise differs from a roux-based sauce in that it uses eggs for thickening, rather than flour and butter.

Example Sentences

“The poached asparagus was elegantly topped with hollandaise sauce.”
“Eggs Benedict is a brunch classic, defined by its hollandaise.”

Notes for Chefs and Students

Use clarified butter for consistent emulsification and cleaner flavor.
Begin with egg yolks and acid over a bain-marie to gently cook and stabilize before adding butter.
Add butter gradually while whisking constantly to maintain a smooth emulsion.
Hold sauce at a warm but not hot temperature (around 60°C/140°F) to avoid splitting.
Practice variations—like adding herbs, wine reductions, or whipped cream—to explore hollandaise sauce derivatives.
