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
Combine small pieces of boiled ham and the heart and inside leaves of lettuce in a salad bowl.
Make the dressing
In a saucepan, mix sour cream, vinegar, salt, butter, sugar, and mustard until smooth.
Boil the mixture, then add the well-beaten egg yolks, stirring carefully until it thickens to a starch-like consistency.
Set the dressing in a cool place or on ice until cold.
Serve
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
- Provides richness and a creamy body to the dressing.
- Egg yolks
- Thicken the dressing when gently heated and help it hold together.
- Vinegar
- Adds acidity that sharpens the flavour of the dressing.
- Mustard
- Adds sharp flavour and helps emulsify the dressing.
- Boiled ham
- Supplies the savoury, meaty body of the salad.
The step that matters
Adding the egg yolks to the boiling mixture. Egg yolks thicken through gentle heat, but if they are added too fast or stirred too little they can scramble into lumps. Stirring carefully keeps the dressing smooth and evenly thickened.
