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.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White or brown bread
- Provides the structure that holds the filling together.
- Butter
- Spread on the bread to add richness and keep the bread from soaking up moisture from the filling.
- Boiled cold salmon
- Provides the main protein and flavour of the filling.
- Tartare sauce
- Adds moisture, tang and richness to the salmon.
- Finely shredded lettuce
- Adds a crisp, fresh texture between the salmon and bread.
The step that matters
Spread the tartare sauce thinly and keep it stiff. A stiff sauce stays in place when the sandwich is pressed and cut, while a thin, runny sauce would soak into the bread and make it soggy.
Swap the lettuce
How well each one fits the dish's main ingredients (bread, butter, salmon, sauce):
- Tomatofits better
- Shallotfits better
- Chivefits better
- Lettucethe original
Fit is the average pairing score against bread, butter, salmon, sauce. Candidates are from the same food group and used in at least 100 recipes.
