Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the sauce and set into a rich, thickened custard when heated.
- Egg whites
- Whipped and folded in to lighten the sauce's texture.
- Sweet cream
- Adds richness and smooth body to the sauce.
- Vinegar
- Supplies acidity that sharpens the flavour of the sauce.
- Flour
- Thickens the sauce as it heats.
The step that matters
Heating the egg yolk mixture. Egg yolks can scramble if overheated or boiled too hard. Stirring over gentle heat keeps the sauce smooth and thickened, and the flour helps stabilise it.
Swap the mustard
