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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and give it a soft, starchy body.
- Eggs
- Add richness and body; the yolks form a creamy dressing base.
- Mustard
- Adds sharp, pungent flavour that cuts through the richness of the yolks.
- Vinegar
- Adds acidity that brightens the salad and balances the creamy yolks.
- Celery
- Adds crisp texture and a fresh, slightly savoury crunch.
The step that matters
Let the potatoes cool before slicing and dressing. Warm potatoes absorb dressing unevenly and can turn mushy when handled. Cooling them firms the starch so the slices hold their shape and take the yolk mixture well.
Swap the potato
