Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled eggs
- Provide the creamy, savoury filling that gives the sandwich body.
- Cold, boiled ham
- Supplies the salty, meaty flavour that forms the bulk of the filling.
- Butter
- Adds fat and a rich layer that keeps the bread from soaking up the filling.
- Mustard
- Adds sharp acidity that cuts through the richness of the eggs and ham.
