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
- Emulsify and thicken the dressing, giving it a creamy body when heated.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the yolks and cream.
- Sweet cream
- Adds richness and a smooth, mild texture to the finished salad.
- Boiled ham
- Provides the savoury, meaty base of the salad.
The step that matters
Boiling the dressing until creamy. Egg yolks thicken as their proteins set with heat, but overheating can scramble them into lumps. Heat gently and stir, then let it cool fully before adding it to the salad.
Swap the lettuce
How well each one fits the dish's main ingredients (ham, vinegar, butter, egg, sugar, mustard, cream):
