Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Enriches the sauce and helps it set as it cooks and thickens.
- Corn starch
- Thickens the liquid into a smooth sauce when heated.
- Sweet cream
- Adds richness and a smooth, silky texture to the sauce.
- Horseradish
- Provides the sharp, pungent flavour that defines the sauce.
- Cider vinegar
- Adds acidity that balances the sharpness of the horseradish.
The step that matters
Finish cooking until thickened. Egg yolk can curdle if it overheats, while the starch needs enough heat to thicken. Cook gently and keep stirring so the sauce thickens smoothly without scrambling.
