Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Egg Salad
Ingredients
Directions
Prepare the dressing
Chop the hard-boiled eggs and sweet pickles into small dice.
Combine vinegar, water, sugar, salt, and butter in a saucepan. Boil the mixture for a few minutes.
Pour the hot mixture over the beaten yolks of 2 eggs. Boil for a few more minutes.
Add cayenne pepper and mustard mixed in water. Stir in cornstarch mixed in water. Boil for a few minutes.
Remove from heat. Pour the mixture into the beaten whites of 2 eggs. Set aside to cool.
Assemble and serve
Once cooled, pour the dressing over the diced eggs and pickles. Fold in whipped cream to taste.
Garnish with finely cut lettuce before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the dressing and whites bind it into a cooked custard base.
- Cornstarch
- Starch thickens the hot vinegar mixture so the dressing becomes smooth and clingy.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Adds acidity that gives the dressing its tang.
- Whipped cream
- Adds fat and lightness, softening the dressing's sharpness and making it creamy.
- Sweet pickles
- Add sweetness and crunch to the diced salad.
The step that matters
Pour the hot mixture over the beaten yolks, then boil again. Egg yolks can scramble if they meet very hot liquid too quickly. Pouring slowly while whisking, then returning to a boil, lets the yolks thicken the dressing smoothly.

Fit is the average pairing score against egg, vinegar, sugar, butter, pepper, mustard, cream. Candidates are from the same food group and used in at least 100 recipes.
