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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the hot dressing into a creamy custard-like base.
- Vinegar
- Adds the sharp acidity that balances the sugar and rich eggs.
- Sugar
- Adds sweetness that offsets the acidity of the vinegar.
- Cornstarch
- Thickens the dressing so it clings to the diced eggs and pickles.
- Whipped cream
- Adds fat and lightness, softening the dressing's texture.
- Sweet pickles
- Contribute sweetness and crunch to the diced salad.
The step that matters
Pouring the hot mixture over the beaten yolks. If the hot liquid is poured in too quickly, or the yolks are not beaten smooth, the eggs can scramble instead of thickening the dressing evenly. Adding the hot mixture gradually while whisking gently tempers the yolks.
Flavor stand-ins for the lettuce

- Lettucethe original
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. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
