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 filling and protein bulk of the sandwich.
Grated cheese: Adds richness and savoury flavour that binds the filling together.
Cream: Moistens the filling so it spreads easily and stays tender.
Brown bread: Forms the structure of the sandwich and holds the filling.
Lettuce leaves: Adds crisp texture and freshness that contrasts with the soft filling.
