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

What each ingredient does

Hard-boiled eggs
Yolks are mashed into a powder that thickens and enriches the dressing.
Butter
Adds richness and a smooth, creamy body to the dressing.
Vinegar
Provides sharp acidity that balances the richness and sweetness of the dressing.
White sugar
Adds sweetness that rounds out the sharpness of the vinegar.
Prepared mustard
Contributes sharp flavour and helps emulsify the dressing.

The step that matters

Mix in the dressing by tossing with a fork.. Tossing gently coats the lettuce evenly without bruising or tearing the leaves, which would release water and make the salad limp.

Swap the lettuce

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

  1. Horseradishfits better
  2. Capsicumfits better
  3. Shallotfits about as well
  4. Lettucethe original

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