Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Yolks mash into a smooth base that gives the sauce body.
- White wine vinegar
- Adds sharpness that balances the richness of the yolks and cream.
- Grated horseradish
- Supplies the sharp, pungent heat that defines the sauce.
- Cream
- Adds moisture and softness, loosening the sauce to a smooth texture.
The step that matters
Gradually add the vinegar while stirring. Adding acid slowly while stirring lets the mashed yolks absorb it evenly, so the sauce becomes creamy instead of separating or turning grainy.
