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 ↓
Cream Dressing
Ingredients
Directions
In a bowl, rub together the butter, vinegar, salt, and mustard if using.
Place the bowl in a saucepan of boiling water over low heat.
Stir the mixture carefully until very hot to prevent the butter from separating.
Add the beaten eggs and stir until thick.
Remove from heat and stir in the cream until smooth.
Allow the dressing to cool completely before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they set gently in the warm mixture, giving it body.
- Butter
- Adds richness and smoothness, which is why it must not separate during heating.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the cream.
- Cream
- Adds richness and a smooth, mellow texture once stirred in off the heat.
The step that matters
Stir the mixture carefully until very hot. Gentle, steady heat in a water bath lets the egg proteins thicken the dressing without scrambling. Heating too fast or unevenly can curdle the eggs or make the butter separate out of the emulsion.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (butter, vinegar, egg, cream):
- Chivefits about as well

- Mustardthe original
Fit is the average pairing score against butter, vinegar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
