Why it works: Lettuce and mustard 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
- Egg yolks
- Thicken the sauce as they cook and give it a rich, creamy body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the sauce.
- Sweet cream
- Adds fat and moisture, making the dressing smooth and mellow.
- Butter
- Adds fat and richness, helping the sauce feel smooth.
- Mustard
- Adds sharp, pungent flavour that complements the ham.
The step that matters
Boil the mixture until it creams. Egg yolks scramble if overheated, so the sauce must be heated gently and stirred until it thickens smoothly; overcooking curdles it into grainy lumps.
Swap the lettuce
How well each one fits the dish's main ingredients (ham, butter, pepper, sugar, mustard, vinegar, egg):

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