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
Infuse the milk
Boil the onion with whole black pepper in milk until the onion is very soft.
Strain the milk over the grated bread and cover it.
After an hour, transfer to a saucepan, add butter, and boil together.
Season with salt and serve.
Alternative method
Alternatively, slice the onion thinly, boil in broth or water until tender, then add bread crumbs to thicken.
Stir in butter, pepper, salt, and cream, and boil until thick and smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale white bread
- Soaked in milk and boiled, it thickens the sauce to a smooth, soft body.
- Milk
- Carries the onion and pepper flavour and forms the body of the sauce.
- Onion
- Softened in milk, it gives the sauce its mild, sweet savoury base.
- Butter
- Added at the end, it enriches the sauce and adds a rounder, silkier mouthfeel.
- Cream
- Optional; adds richness and a smoother, softer texture to the finished sauce.
The step that matters
Boil until thick and smooth. Starch from the bread thickens as it heats and hydrates. Boiling with the butter should be done gently and stirred, since scorching or too-rapid boiling can make the sauce catch on the pan or turn lumpy.
Swap the onion
How well each one fits the dish's main ingredients (milk, pepper, bread, butter, cream):
