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 body.
- Butter
- Adds richness and a smooth, silky texture to the dressing.
- Flour
- Thickens the dressing so it holds together rather than running.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and cuts its richness.
- Milk
- Adds moisture and softness, making the dressing creamy.
The step that matters
Cook until thickened. Egg-based dressings thicken as the egg proteins set, but if the heat is too high the eggs can scramble and curdle. Gentle heat in a double boiler keeps the dressing smooth.
Swap the orange

Fit is the average pairing score against walnut, grape, lettuce, egg, milk, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
