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 Boiled
Ingredients
Directions
Make the dressing base
In a pot, combine vinegar and salt, then bring to a boil.
If the vinegar is too strong, dilute it with water.
In a bowl, mix butter, sugar, mustard, and sour cream until smooth.
Gradually add the beaten eggs to the mixture.
Slowly pour in the boiling vinegar while stirring.
Cook and finish
Return the mixture to the heat and cook until it thickens to a custard-like consistency.
Strain the mixture and fold in the whipped cream.
Store in a jar with a glass cover.

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 cook into a custard-like texture.
- Butter
- Adds richness and a smooth, creamy mouthfeel to the dressing.
- Vinegar
- Provides the sharp acidity that defines the dressing's flavor.
- Sour cream
- Adds tang and body, softening the sharpness of the vinegar.
- Whipped cream
- Lightens the cooked dressing and adds a soft, airy richness.
- Sugar
- Balances the acidity of the vinegar with sweetness.
The step that matters
Return the mixture to the heat and cook until it thickens. Egg proteins set as they heat, thickening the dressing into a custard. Heating too fast or too long can scramble the eggs, so cook gently while stirring and stop once it coats a spoon.
Swap the mustard
