Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour

Thickens the dressing as its starch swells when heated.

Egg

Thickens and enriches the dressing as the cooked egg sets.

Vinegar

Adds acidity that sharpens the flavor and cuts the richness.

Butter

Adds richness and a smooth, rounded mouthfeel.

Sugar

Adds sweetness that balances the sharpness of the vinegar.

Neufchatel cheese

Adds creaminess and body to the dressing.
