Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp leaves that the dressing coats.
- Vinegar
- Adds acidity that brightens the flavor of the dressing.
- Oil
- Adds fat that carries flavor and gives the leaves a light coating.
The step that matters
Add the oil just before serving. Oil and vinegar do not stay mixed for long, so the dressing separates if it sits. Adding the oil at the last moment keeps it evenly combined and stops the lettuce from becoming soggy.
Swap the white pepper
How well each one fits the dish's main ingredients (lettuce, vinegar, cream):
- Tarragonfits better
- Capersfits better
- Peppermintfits better
- White pepperthe original
Fit is the average pairing score against lettuce, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
