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 rich, delicate flavour of the salad.
- Lettuce
- Adds crisp texture and bulk to the salad base.
- Ripe tomatoes
- Contribute juicy moisture and fresh acidity to the salad.
- Oil
- Carries flavour and adds a smooth, rich mouthfeel to the dressing.
- Lemon juice
- Adds bright acidity that balances the richness of the roe and oil.
The step that matters
Separate the grains by washing them in vinegar.. Cooked roe must be handled gently so the grains stay intact; vinegar helps firm the proteins and keeps the grains from breaking into a mush.
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.
