Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Provides the savory meaty base and bulk of the filling.
- Pickles
- Adds acidity and sharp flavor that cuts through the rich ham and butter.
- Melted butter
- Adds fat and moisture so the filling spreads smoothly and stays rich.
- French or german mustard
- Contributes sharp heat and tang that brightens the filling.
- Rye bread
- Provides a sturdy, slightly sour structure to hold the filling.
The step that matters
Mix until smooth. If the mixture is not blended well, the melted butter may stay in pools and the filling can be greasy or uneven. Thorough mixing emulsifies the fat with the moist pickles and mustard, giving an even, spreadable texture.
