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 ↓
Cucumber Sauce
Ingredients
Directions
Prepare the cucumbers
Grate the cucumbers and remove the large seeds.
Mix the cucumber pulp with salt and let it drain overnight.
Squeeze the pulp dry.
Make the sauce
In a bowl, combine the cucumber pulp, horseradish, mustard seed, celery seed, black pepper, sugar, and additional salt if needed.
Add enough cider vinegar to achieve the desired consistency.
Transfer the sauce to a large-mouth bottle and seal well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the bulk of the sauce and its fresh, mild body once drained of excess water.
- Horseradish
- Supplies the sharp, pungent heat that defines the sauce.
- Cider vinegar
- Adds acidity and sets the final consistency and tang of the sauce.
- Sugar
- Balances the acidity and sharp heat with a touch of sweetness.
The step that matters
Squeeze the pulp dry. Cucumbers are mostly water. If excess liquid stays in the pulp, the sauce turns thin and watery and the vinegar cannot set the consistency you want. Draining salted pulp and pressing it dry concentrates the flavour and keeps the texture stable.
Swap the celery
How well each one fits the dish's main ingredients (cucumber, horseradish, mustard, pepper, sugar, cider, vinegar):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against cucumber, horseradish, mustard, pepper, sugar, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
