Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and 41,516 recipes mention both. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Hollandaise Sauce
Ingredients
Directions
Prepare the flavouring
Soak horseradish in elder‑flower vinegar for 10 minutes.
Strain the vinegar through a fine sieve to extract flavor.
Make the sauce
Reduce velouté sauce to half its quantity.
Beat egg yolks and cream together, then mix with reduced velouté sauce.
Heat gently until the sauce thickens, but do not boil.
Strain the sauce into a bain‑marie.
Mix in butter, cayenne pepper, and salt, then set aside.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and add richness as they set gently with heat.
- Cream
- Adds moisture and richness, softening the texture of the sauce.
- Velouté sauce
- Provides the body and base that is concentrated by reduction.
- Butter
- Adds fat for silky mouthfeel and a glossy finish.
- Horseradish
- Contributes a sharp, pungent aroma and flavour to the sauce.
The step that matters
Heat gently until the sauce thickens, but do not boil. Egg yolks thicken through gentle heat, but above about 70°C they scramble, leaving a grainy, curdled sauce that cannot be recovered.
Flavor stand-ins for the horseradish
How well each one fits the dish's main ingredients (vinegar, sauce, egg, cream, butter, pepper):
- Capsicumbetter flavor fit
- Mustardabout as good a flavor fit
- Horseradishthe original
- Shallotabout as good a flavor fit
Fit is the average pairing score against vinegar, sauce, egg, cream, butter, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
