Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Horseradish Hollandaise Sauce
Ingredients
Directions
Wash the butter and divide it into three pieces.
In a saucepan, combine one piece of butter, vinegar, egg yolks, and salt.
Place the saucepan in a larger pot of boiling water and stir constantly until the butter melts.
As the mixture thickens, add the second piece of butter, then the third piece.
Remove from heat.
Stir in the grated horseradish and the heavy cream, beating until stiff.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and thicken the sauce as they heat gently.
- Butter
- Provides fat that makes the sauce rich and silky when emulsified.
- Vinegar
- Adds acidity that balances the richness of the butter and yolks.
- Grated horseradish root
- Adds sharp, pungent flavor that defines the sauce.
- Heavy cream
- Adds moisture and softness to the finished sauce.
The step that matters
Adding the butter while the yolks thicken. Butter must be added gradually while the yolks are warm, so it emulsifies into the sauce. Adding it too fast or with too much heat can split the sauce into greasy liquid and scrambled egg.
