Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Cucumber Salad
Ingredients
Directions
Prepare the vegetables
Peel the cucumber, cut it in half, and scoop out the seeds to create a boat shape.
Soak the cucumber halves in ice water until needed.
Chop the tomatoes, celery, cucumber, and onion into small pieces.
Season the chopped vegetables with salt and pepper.
Make the dressing
In a bowl, cream together the sugar, dry mustard, and coarse sea salt with the butter.
Add the egg yolk and beat until smooth.
Stir in the sweet or sour cream and vinegar, mixing in the order given.
Cook the dressing until smooth, then combine with the seasoned vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the dressing and gives it a smooth, rich body.
- Sweet or sour cream
- Adds fat and creaminess, giving the dressing its body and mild tang.
- Vinegar
- Adds acidity that brightens the dressing and balances the sweetness.
- Sugar
- Adds sweetness that balances the vinegar and sharpness of the mustard.
- Butter
- Adds fat and richness to the dressing base.
The step that matters
Cook the dressing until smooth. Egg yolk can curdle or scramble if heated too quickly or too hot. Cooking gently and stirring keeps the dressing smooth and thick, so it combines evenly with the vegetables.
Swap the onion
