Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they cook and set, giving it a creamy, rich body.
- Egg whites
- Add beaten structure and lightness to the dressing mixture.
- Whipped cream
- Adds moisture and a light, airy richness to the cooled dressing.
- Sugar
- Adds sweetness that balances the mustard, cayenne and vinegar.
- Vinegar
- Adds acidity that sharpens the dressing and cuts through its richness.
- English walnuts
- Provide crunch and a fatty, nutty flavour against the grapes.
The step that matters
Cooking the egg mixture until it boils. Eggs thicken as their proteins set with heat, but overheating can curdle them into lumps. Stir constantly over medium heat and cool before folding in the whipped cream.
Swap the grape
How well each one fits the dish's main ingredients (walnut, egg, butter, sugar, mustard, pepper, vinegar):
- Lemonfits better
- Figfits better
- Cherryfits about as well
