Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Adds moisture and richness to the bread, softening it against the filling.
- Tomato
- Adds moisture and acidity that keeps the filling juicy.
- Egg
- Adds richness and a soft, creamy texture to the filling.
- Black olives
- Add salty, savory flavor that balances the filling.
- Anchovies
- Add concentrated salty, savory depth to the filling.
- Vinegar
- Adds acidity that brightens the flavors of the vegetables and egg.
The step that matters
Remove part of the bread to allow space for the filling. Hollowing the roll gives the filling room to sit inside without spilling out. Removing too little makes the sandwich overstuffed and messy, while removing too much leaves the bread too thin to hold the juices.
Swap the onion
How well each one fits the dish's main ingredients (olive, pepper, tomato, egg, vinegar):
- Capsicumfits better
- Cucumberfits better
- Eggplantfits better
- Onionthe original
