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

What each ingredient does

Cold cooked mutton: Provides the main meaty filling and bulk of the sandwich.
Capers: Add a sharp, briny acidity that cuts through the rich meat.
Lemon juice: Adds brightness and acidity that balances the richness of the mutton.
Buttered whole wheat bread: Gives a soft, moist base and a toasty, buttery flavor contrast.
