Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides the base that holds the filling and soaks up moisture from the spread.
- Butter or mayonnaise
- Adds fat and moisture, and forms a barrier that keeps the bread from soaking through.
- Cooked chicken
- Supplies the main meaty texture and savoury flavour of the filling.
- Hard-boiled eggs
- Add body and a soft, creamy texture when mashed into the filling.
- Cream
- Adds moisture and richness, giving the filling a smoother, softer texture.
- Cooked chicken livers
- Contribute a rich, deep flavour and a smooth, spreadable texture when chopped fine.
The step that matters
Chop or pound meats to a paste.. If the meat is left in coarse pieces, the filling will not spread evenly or hold together in the sandwich. Fine, uniform chopping lets the fat and moisture from the dressing bind the meat into a smooth filling.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (bread, butter, lettuce, chicken, celery, pepper, ham):
- Mustardthe original
- Leekfits about as well
- Capsicumfits about as well
- Tomatofits less well
Fit is the average pairing score against bread, butter, lettuce, chicken, celery, pepper, ham. Candidates are from the same food group and used in at least 100 recipes.
