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 ↓
Ham Salad
Ingredients
Directions
Prepare the salad
In a salad bowl, combine the bits of boiled ham with the lettuce leaves.
Make the dressing
In a saucepan, mix the sour cream, vinegar, pepper, salt, butter, sugar, and mustard.

Set the dressing in a cool place or on ice until cold.
Assemble
Pour the dressing over the salad and mix well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Adds richness and a creamy body to the dressing.
- Egg yolks
- Thicken the dressing as they set with gentle heat, giving it body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the cream.
- Mustard
- Adds sharp, pungent flavour that complements the ham and cream.
- Boiled ham
- Provides savoury, salty meat flavour and substance to the salad.
The step that matters
Stirring the egg yolks into the boiled mixture. Egg yolks thicken by gentle heat, but if the mixture boils too hard after they are added, they can scramble into lumps. Stir carefully and keep the heat controlled until it thickens.
