Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides the structure and body that holds the filling together.
- Butter
- Adds fat and richness, and helps keep the bread from soaking up the filling.
- Liebig's extract of meat
- Supplies concentrated savory meat flavour as the main filling.
- Mustard
- Adds sharp acidity that cuts through the richness of the meat extract.
