Why it works: Pepper and lemon 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 ↓
Shrimp Salad
Ingredients
Directions
Make the dressing
In a bowl, mix the hard boiled and raw egg yolks until smooth.
Slowly beat in the oil, alternating every third tablespoon with vinegar and lemon juice.
Once the mixture is light, add salt and cayenne pepper to taste.
Assemble and serve
Do not add the dressing to the shrimp until ready to serve.
In winter, mix in chopped celery equal to the amount of shrimp.
In summer, place shrimp in the center of a dish, pour dressing over, and garnish with lettuce.
Chill the dressing in the ice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their lecithin helps the oil and vinegar blend into a smooth, thick emulsion.
- Oil
- Provides fat that gives the dressing a rich, silky body.
- Vinegar
- Adds acidity that sharpens the flavor and balances the richness of the oil.
- Lemon juice
- Adds bright acidity that lifts the flavor of the dressing.
- Shrimp
- Forms the main body of the salad, supplying its protein and bulk.
The step that matters
Slowly beat in the oil, alternating with vinegar and lemon juice. Oil must be added gradually so the egg yolks can disperse it into tiny droplets. Adding it too fast causes the emulsion to break, leaving a greasy, separated dressing instead of a smooth, thick one.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (shrimp, egg, pepper, vinegar, lemon, lettuce):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- Celerythe original
Fit is the average pairing score against shrimp, egg, pepper, vinegar, lemon, lettuce. Candidates are from the same food group and used in at least 100 recipes.
