Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Thickens the dressing as it cooks and gives it a rich body.
Flour
Thickens the dressing with starch as it cooks, giving it a smooth consistency.
Sugar
Adds sweetness that balances the sharpness of the vinegar.
Vinegar
Provides acidity that gives the dressing its tangy flavour.
Tomatoes
Supply the fresh, juicy base that the warm dressing is served over.

The step that matters

Cook the mixture until it thickens. The egg and flour must be heated gently while stirring; too little heat leaves the dressing thin, while overheating can scramble the egg and leave lumps.

Swap the tomato

How well each one fits the dish's main ingredients (lettuce, egg, sugar, flour, vinegar, mustard):

  1. Beetrootfits better
  2. Horseradishfits better
  3. Shallotfits better
  4. Tomatothe original

Fit is the average pairing score against lettuce, egg, sugar, flour, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
