Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roe
- Provides the main protein and the flaky, delicate grains that make up the salad.
- Lettuce
- Adds crisp texture and bulk to the salad base.
- Tomatoes
- Add moisture and a juicy, slightly acidic freshness.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the roe.
The step that matters
Separate the grains by washing them in vinegar. Cooked roe must be gently separated into distinct grains so it does not clump or break into a mush. Vinegar helps firm the proteins and keeps the grains from sticking together in the salad.
Swap the tomato
How well each one fits the dish's main ingredients (roe, lettuce, lemon, pepper):
- Spinachfits better
- Cucumberfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against roe, lettuce, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
