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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main protein, setting firm as they cook and forming the centre of the dish.
- Bread
- Gives a crisp, sturdy base that holds the egg and absorbs runny yolk.
- Butter
- Adds richness and flavour to the toast and helps it brown lightly.
- Chili sauce
- Adds sweetness, acidity and heat that contrast with the rich egg and butter.
The step that matters
Steam or poach the eggs until cooked. Eggs cook through at a precise point: undercooking leaves the white runny, while overcooking makes the yolk chalky and rubbery. Cooking them just until set keeps the yolk soft and the whites tender.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, bread, butter, sauce):
- Shallotfits better
- Asparagusfits better
- Chivefits better
- Lettucethe original
Fit is the average pairing score against egg, bread, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
