Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sandwich loaf
- Provides the structure that holds the layered fillings together.
- Sweet butter
- Adds richness and helps the toast brown and taste savoury.
- Cooked chicken
- Supplies the main savoury filling and most of the substance.
- Bacon or ham
- Adds salty, smoky flavour and fat to the layers.
- Mayonnaise
- Adds moisture and richness that bind the fillings.
- Lettuce
- Adds crisp texture and freshness against the soft fillings.
The step that matters
Toasting and buttering the bread. Toast must be golden and buttered so it stays crisp. Butter forms a fat barrier that slows moisture from the chicken and mayonnaise soaking into the bread.
Swap the lettuce
How well each one fits the dish's main ingredients (butter, chicken, pepper, ham):
- Capsicumfits better
- Potatofits better
- Onionfits better
- Lettucethe original
Fit is the average pairing score against butter, chicken, pepper, ham. Candidates are from the same food group and used in at least 100 recipes.
