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 ↓
Bread Sauce
Ingredients
Directions
Boil the chopped onion in the milk until tender.
Strain the milk over the bread crumbs and cover to let them soak.
Beat the soaked bread crumbs thoroughly.
Add salt, butter, cayenne pepper, and mace to the mixture.
Bring to a boil and serve.
If the sauce is too thick, thin it with cream after making.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dry bread crumbs
- Soak up the milk and thicken the sauce into a smooth, spoonable body.
- Milk
- Liquid that softens the bread crumbs and forms the sauce base.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
- Onion
- Infuses the milk with savory flavor as it simmers until tender.
The step that matters
Beating the soaked bread crumbs thoroughly. Soaked crumbs left in lumps give an uneven, grainy texture. Thorough beating breaks them down so the starch and liquid combine into a smooth, cohesive sauce.
Swap the mace
How well each one fits the dish's main ingredients (milk, bread, onion, butter, pepper):
- Parsleyfits better
- Garlicfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against milk, bread, onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
