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

What each ingredient does

Cooked chicken: Provides the main protein and bulk of the filling.
Hard-boiled egg: Adds richness and a soft, creamy texture to the filling.
Mayonnaise: Adds fat and moisture, binding the filling together.
Celery: Adds crisp texture and a fresh, mild crunch.
Butter: Adds fat and flavor to the bread, helping it brown and resist sogginess.
