Why it works: Mustard and celery 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 ↓
Celery, Mayonnaise
Ingredients
Directions
Make the mayonnaise
In a bowl, beat the egg yolk, mustard, salt, pepper, lemon juice, and a little water together.
Slowly pour in the olive oil drop by drop while continuing to beat the mixture.
Add a small spoonful of boiling water to the mayonnaise.
Assemble and serve
Wash and wipe the celery, then cut it into pieces in a salad bowl.
Pour the mayonnaise over the celery, mix well, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and water into a thick, stable mayonnaise.
- Olive oil
- Provides the fat that gives the mayonnaise its rich body and texture.
- Lemon juice
- Adds acidity that brightens the flavour and helps stabilise the emulsion.
- Celery
- Supplies the crisp texture and fresh flavour of the salad.
The step that matters
Slowly pour in the olive oil drop by drop while continuing to beat the mixture.. Oil must be added very gradually so the droplets are fully dispersed by the egg yolk's lecithin. Pouring too fast breaks the emulsion, leaving the mayonnaise runny and separated.
Swap the mustard
