Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp, bulky base of the salad, with the layers giving body and structure.
- Mayonnaise
- Adds fat and creamy moisture that coats the greens and binds the layers.
- Sugar
- Adds sweetness that balances the tang of the mayonnaise and the salty cheese and bacon.
- Parmesan cheese
- Adds salty, savory flavor and a little fat to the top layer.
- Bacon
- Adds savory, smoky flavor and fat, contrasting with the crisp greens.
The step that matters
Keep the layers intact and refrigerate overnight without tossing. Sugar on the mayonnaise draws moisture slowly over time, softening the greens. Leaving the layers undisturbed keeps their texture and appearance distinct as the salad chills.
Swap the peas
How well each one fits the dish's main ingredients (lettuce, celery, pepper, sugar, parmesan cheese):
- Beansfits better
- Walnutfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against lettuce, celery, pepper, sugar, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
