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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled egg
- Adds richness and body, helping the spread hold together and turn creamy.
- American cheese
- Melts and blends into a smooth, spreadable base with a savory flavor.
- Melted butter
- Adds fat for a silkier texture and a richer mouthfeel.
- Made mustard
- Adds sharp flavor that cuts through the richness of the cheese and egg.
- Vinegar
- Adds acidity that brightens the flavor and balances the fat.
The step that matters
Add the ingredients gradually while beating continuously. Adding liquids and fats slowly while beating lets them emulsify into one smooth, creamy mixture. Adding everything at once can leave the spread greasy or lumpy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, cheese, butter, sauce, bread):
- Mustardthe original
- Capsicumfits about as well
- Shallotfits less well
- Tomatofits less well
Fit is the average pairing score against egg, vinegar, cheese, butter, sauce, bread. Candidates are from the same food group and used in at least 100 recipes.
