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 main filling, adding richness and a soft, creamy texture.
- Chopped cress
- Adds a fresh, peppery aroma that cuts through the richness of the egg.
- Bread
- Forms the structure and holds the egg filling between two slices.
- Butter
- Adds fat and flavor to the bread, helping the filling taste rich.
The step that matters
Mash the yolks until smooth. Working the yolks fully smooth with the salt and cress gives an even spread. Lumps of yolk can tear soft bread and leave pockets without seasoning.
