Why it works: Vinegar and lettuce are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,370 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Shrimps
Ingredients
Directions
Prepare
Dry the shrimps on a towel without crushing the leaves.
Cut the lettuce into moderate-sized pieces and place in a salad bowl.
Remove any shell pieces from the shrimps and pile them on top of the lettuce.
Make the dressing
In a bowl, whisk the yolks of two eggs and gradually add the salad oil until thick.
Stir in the vinegar and white pepper, heating until well blended.
Assemble and serve
Pour the dressing over the shrimps and garnish with reserved lettuce leaves.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks emulsify with the oil, thickening the dressing into a creamy, stable sauce.
- Salad oil
- Forms the body of the dressing, adding richness and a smooth mouthfeel as it is whisked in.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- Shrimps
- Provide the main protein and mild sweet flavour of the salad.
The step that matters
Adding the salad oil to the yolks. Oil must be added slowly while whisking, so the yolks can emulsify it. Adding it too fast causes the dressing to break and separate instead of becoming thick.
Swap the white pepper
How well each one fits the dish's main ingredients (shrimp, egg, vinegar, lettuce):
- Tarragonfits better
- Capersfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against shrimp, egg, vinegar, lettuce. Candidates are from the same food group and used in at least 100 recipes.
