Why it works: Horseradish and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare
In a bowl, combine the cut cabbage, chopped celery, and grated horseradish. Season with coarse sea salt to taste.
In a separate bowl, mash the hard-boiled egg yolks into a smooth paste. Mix in the oil, mustard, pepper, and vinegar until well combined.
Dress and serve
Stir the dressing into the cabbage mixture a few moments before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mashed into a smooth paste, they emulsify the oil and vinegar into a creamy dressing.
- Oil
- Adds richness and a silky texture to the dressing.
- Vinegar
- Adds acidity that brightens the slaw and balances the richness of the oil.
- Cabbage
- Forms the crisp, bulky base of the slaw that the dressing coats.
- Horseradish
- Contributes sharp, pungent heat that gives the slaw its characteristic bite.
The step that matters
Stir the dressing in just before serving. Vinegar and salt draw water out of cabbage over time, so the slaw turns limp and watery if dressed too early. Adding the dressing shortly before serving keeps the cabbage crisper.
Swap the celery
How well each one fits the dish's main ingredients (cabbage, horseradish, egg, mustard, pepper, vinegar):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against cabbage, horseradish, egg, mustard, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
