Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers: Provide the crisp, watery bulk of the filling, giving it fresh texture and a cool flavour.
Nut meats: Add a crunchy texture that contrasts with the soft cucumber and mayonnaise.
Mayonnaise: Adds fat and moisture, binding the chopped vegetables into a spreadable filling.
White onion: Adds a sharp, aromatic bite that brightens the filling.

The step that matters

Drain the cucumbers. Cucumbers hold a lot of water. If they are not drained well after soaking, the extra liquid thins the mayonnaise and makes the bread soggy.

Swap the onion
