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
- Bread crumbs
- Absorb the flavoured milk and swell, thickening the sauce into a smooth body.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
- Flour
- Binds with the butter so the sauce thickens evenly without lumps.
- Milk
- Carries the onion and peppercorn flavours and forms the base of the sauce.
The step that matters
Adding the butter and flour mixture. Flour rubbed into butter must be fully mixed in before boiling, or it can form lumps and leave the sauce uneven in texture. Boiling briefly after adding flour also cooks out its raw taste and lets the starch thicken fully.
Swap the onion
How well each one fits the dish's main ingredients (milk, bread, butter, flour, cream):
- Potatofits better
- Leekfits better
- Arrowrootfits about as well
- Onionthe original
Fit is the average pairing score against milk, bread, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
