Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides richness and a smooth, creamy body to the dressing.
- Flour
- Thickens the cream as it heats, giving the dressing body.
- Egg whites
- Beaten whites are folded in to add lightness and airiness to the dressing.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the dressing its tang.
- Butter
- Adds fat for a rich mouthfeel and smooth flavour.
The step that matters
Add the flour mixture to the cream, stirring steadily. Starch from flour can clump into lumps if added without constant stirring. Steady stirring disperses the starch so it thickens the cream evenly as it heats.
