Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides the rich, liquid base that gives the dressing its body.
- Flour
- Starch thickens the cream as it heats, giving the dressing body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
- Butter
- Adds fat for a smooth, rich mouthfeel.
- Egg whites
- Beaten whites add lightness and body to the dressing.
The step that matters
Pour the mixture over the beaten egg whites. The hot mixture can partly cook the egg whites and deflate their foam. Pouring slowly while stirring gently keeps the dressing light and evenly smooth.
Swap the mustard
