Why it works: Butter and bread 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 ↓
A Dbessing Fob Sandwiches
Ingredients
Directions
Make the dressing
In a bowl, combine the butter, mustard, sweet oil, pepper, salt, and egg yolk. Mix until smooth.
Chill the mixture in the refrigerator.
Assemble the sandwiches
Finely chop the tongue, ham, and optional cold chicken.
Spread the dressing on a slice of bread. Layer the chopped meats on top, then add another slice of bread and press together firmly.
Trim the edges to make the sandwiches uniform in size.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, giving the dressing a smooth, spreadable body.
- Egg yolk
- Emulsifies the butter and oil so the dressing holds together smoothly.
- Mixed mustard
- Adds sharp, tangy flavour that cuts through the richness of the meats and butter.
- Tongue
- Provides the main meaty flavour and texture in the filling.
- Ham
- Adds savoury, salty flavour and chewy texture to the filling.
The step that matters
Chill the dressing before assembling. Chilling firms the butter-and-yolk emulsion so it stays thick and spreadable instead of soaking into the bread.
Swap the mustard
How well each one fits the dish's main ingredients (butter, pepper, egg, ham, chicken, bread):
- Capsicumfits better

- Potatofits about as well
- Mustardthe original
Fit is the average pairing score against butter, pepper, egg, ham, chicken, bread. Candidates are from the same food group and used in at least 100 recipes.
