Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main filling, setting firm when boiled and holding the sandwich together.
- Butter
- Adds fat and richness, and keeps the bread from soaking up moisture from the egg.
- Bread
- Gives structure and a base that holds the sliced egg filling.
- Dry mustard
- Adds a sharp, pungent flavour that lifts the mild taste of the egg.
The step that matters
Transfer the eggs to cold water. Plunging boiled eggs into cold water stops the cooking quickly, which prevents a grey-green ring forming around the yolk and makes the shell easier to peel.
Swap the mustard
How well each one fits the dish's main ingredients (egg, bread, butter, pepper):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Mustardthe original
Fit is the average pairing score against egg, bread, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
