Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried tomatoes
- Soaking softens them and adds concentrated, chewy tomato flavor to the sandwich.
- Olive oil
- Carries the basil and herb flavors and gives the pesto a smooth, emulsified body.
- Pine nuts
- Add richness and body to the pesto as they blend into a creamy texture.
- Fresh basil leaves
- Provide the aromatic herb flavor that defines the pesto.
- Kalamata olives
- Add salty, briny savoriness that balances the sweet tomatoes.
- Arugula
- Adds a peppery bite and fresh contrast to the rich filling.
The step that matters
Soaking the dried tomatoes. Dried tomatoes that are not fully softened stay tough and leathery in the sandwich. Covering them completely with boiling water and waiting until they are soft lets them rehydrate evenly, and patting them dry keeps excess water from soaking the bread.
Flavor stand-ins for the arugula

Fit is the average pairing score against tomato, bread, basil, olive, chicken, garlic, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
