Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mayonnaise
- Binds the shrimp mixture and adds moisture and richness to the filling.
- Canned shrimp
- Provides the main protein and savory filling for the tomatoes.
- Firm tomatoes
- Act as hollow edible cups that hold the filling and add acidity and moisture.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (shrimp, lettuce, tomato, celery):
- Okrafits better
- Capsicumfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against shrimp, lettuce, tomato, celery. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
