Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Provides the structure for the sandwich, and its dryness lets the butter soak in without turning soggy.
- Butter
- Adds fat and richness to the bread, carrying flavour and helping the slices stay moist.
- Ham
- Supplies the savoury, salty filling that gives the sandwich its main flavour.
- Mixed mustard
- Adds sharp, acidic heat that cuts through the richness of the butter and ham.
The step that matters
Press the sandwiches together firmly. Firm pressing compresses the layers so the filling stays in place and the bread holds together when cut. Pressing too gently leaves gaps that let the filling slide out.
Swap the parsley
How well each one fits the dish's main ingredients (bread, butter, ham, mustard):
- Capersfits better
- Celeryfits about as well
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against bread, butter, ham, mustard. Candidates are from the same food group and used in at least 100 recipes.
