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

What each ingredient does

Lettuce
Forms the leafy bulk of the salad and carries the dressing.
Egg yolks
Rubbed fine, they enrich the dressing and give it a creamy body.
Vinegar
Adds sharp acidity that balances the richness of the yolks and butter.
Butter
Melted into the warm vinegar, it adds fat and a smoother, rounder mouthfeel.

The step that matters

Pouring the warm vinegar mixture over the lettuce. The vinegar and butter must be melted and warm, not boiling, so the mixture coats the leaves evenly and the lettuce wilts slightly without being scorched or turning limp too quickly.

Swap the lettuce

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

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

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