Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cucumber Sandwiches
Ingredients
Directions
Prepare the cucumber
Peel the cucumber and slice it thinly.
Season the cucumber liberally with coarse sea salt and let it drain on a fine sieve for about 1 hour.
Dry the cucumber thoroughly and place it in a bowl.
Sprinkle the cucumber with pepper, salad oil, lemon juice, or vinegar to taste.
Assemble and serve
Spread creamed butter on thin slices of bread.
Cut out rounds of bread and place slices of cucumber between two rounds.
Press the sandwiches together and arrange them slightly overlapping on a napkin.
Garnish with parsley and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumber
- Provides the fresh, crisp filling that forms the body of the sandwich.
- Creamed butter
- Adds fat and richness and creates a moisture barrier against the bread.
- White or brown bread
- Forms the structure that holds the filling and gives the sandwich its shape.
- Salad oil
- Adds fat and a smooth mouthfeel to the dressed cucumber.
- Lemon juice
- Adds acidity that brightens the flavour of the cucumber.
The step that matters
Drain and dry the cucumber thoroughly. Salting draws water out of the cucumber through osmosis. If moisture remains, it soaks into the bread and makes the sandwiches soggy, so the cucumber must be dried well before assembly.
Swap the cucumber
How well each one fits the dish's main ingredients (butter, bread, lemon, vinegar, pepper):

- Mustardfits about as well
- Cucumberthe original
Fit is the average pairing score against butter, bread, lemon, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
