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 ↓
Cream Dressing III
Ingredients
Directions
Make the dressing
In a bowl, mix the egg yolks (or whole eggs), salt, mustard, sugar, black pepper, and flour until well combined.
Gradually add the vinegar and butter, mixing thoroughly.
Heat the mixture until it comes to a boil.
Finish and serve
Once cooled, thin the dressing with a little cream before serving.

Flour and butter 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
- Thicken the dressing as they set with heat and add richness.
- Butter
- Adds fat for a smooth, rich mouthfeel.
- Vinegar
- Provides the sharp acidity that defines the dressing.
- Flour
- Stabilizes the emulsion and helps give the dressing body.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Heating until it boils. Egg proteins thicken the dressing as they heat, but overheating can scramble them into lumps. Stir steadily and remove from heat once it reaches a boil.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, flour, vinegar, butter):

Fit is the average pairing score against egg, sugar, pepper, flour, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
