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
- Eggs
- Poached eggs are the centerpiece, and the yolk mixture binds the coating around them.
- Butter
- Fat that softens the onion and carries flavor into the base before the flour goes in.
- Flour
- Thickens the stock into a stiff sauce-like mixture that holds the eggs in a coating.
- White stock
- Liquid that gives the flour-butter base body and savory flavor.
- Stale bread crumbs
- Form a crisp, browned outer shell when fried in deep fat.
The step that matters
Cook the base for one minute, then cool it before coating. The beaten yolks are a binder that sets with heat, so the mixture must be cooked briefly and cooled enough to handle. If it stays hot or is overcooked, it can scramble or become too stiff, and the coating may split or fall off in the fat.
Swap the onion
