Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the dressing as they cook, giving it a custard-like body.
- Rich milk
- Adds moisture and richness, softening the dressing's texture.
- Butter (in the method)
- Adds fat for richness and a smooth, rounded mouthfeel.
- Vinegar
- Provides acidity that gives the dressing its sharp, tangy bite.
- Sugar
- Adds sweetness that balances the vinegar's sharpness.
- Mustard
- Adds sharp, pungent flavor to the dressing.
The step that matters
Cooking over boiling water while stirring constantly. Egg proteins set gradually as they heat. Stirring constantly and keeping the heat gentle spreads the warmth evenly, so the custard thickens smoothly instead of curdling or scrambling on the bottom of the bowl.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, milk, egg, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Asparagusfits about as well
