Why it works: Vinegar and mustard 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 ↓
Salad Dressing
Ingredients
Directions
Make the dressing
Beat the eggs in a large bowl until very stiff.
Add the sweet cream and salt, and beat thoroughly.
Mix the mustard with a little vinegar to avoid lumps, then add it along with the remaining vinegar and melted butter.
Beat again until well combined.
Cook and store
Set the bowl in a kettle of water.
Boil until the dressing thickens.
Store in a cool place; it will keep for weeks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten stiff, they form the structure that holds the dressing together.
- Sweet cream
- Adds moisture and richness, softening the dressing's texture.
- Sharp vinegar
- Adds acidity that gives the dressing its tangy flavour.
- Mustard
- Adds sharp aroma and helps stabilise the emulsion.
- Melted butter
- Adds fat, contributing richness and a smooth, silky texture.
The step that matters
Boil until the dressing thickens. Heat cooks the egg proteins so they set and thicken the dressing. Too little heat leaves it runny, while overheating can curdle the eggs and break the sauce.
