Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish, with the cooked whites and yolks forming the base for the dressing.
- Vinegar
- Adds sharp acidity that balances the sweetness and richness of the dressing.
- Sugar
- Balances the sharpness of the vinegar, adding sweetness to the dressing.
- Butter
- Adds fat and richness, giving the dressing a smooth, rounded flavour.
- Flour
- Thickens the liquid dressing as it heats, giving it body that clings to the eggs.
The step that matters
Whisking in the flour. Flour thickens when it is whisked into hot liquid and given time to cook. Adding it while the liquid is only lukewarm, or leaving lumps, can leave the dressing thin or grainy. Keep whisking as it heats so the starch disperses evenly.
