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, setting it into a custard-like texture.
- Butter
- Adds richness and a smooth, silky mouthfeel to the dressing.
- Milk or cream
- Adds moisture and richness, helping the dressing become smooth and creamy.
- Vinegar
- Adds acidity that gives the dressing its tangy flavour.
The step that matters
Cook the dressing over boiling water until thick as custard. Eggs thicken when heated gently. Stirring constantly over a steady water bath keeps the heat even, so the eggs set smoothly instead of scrambling or curdling.
Swap the mustard
