Why it works: Mustard and horseradish 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 ↓
Spanish Pickles
Ingredients
Directions
Prepare the vegetables
Sprinkle cucumbers and green peppers with coarse sea salt and let stand for 24 hours.
Place the cucumbers and peppers in a bag and drain overnight.
Make the brine and pickle
In a large pot, combine cider vinegar, turmeric, white ginger, ground mustard, horseradish, celery seed, salad oil, and brown sugar.
Heat the mixture until the sugar dissolves, then let it cool.
Pour the cooled vinegar mixture over the drained cucumbers and peppers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the pickles and give them their crisp, crunchy texture.
- Cider vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavour.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness and depth of flavour.
- Ground mustard
- Adds pungent flavour and a sharp, sinus-clearing bite to the brine.
- Salad oil
- Adds fat that softens the brine's sharp edge and carries flavour.
The step that matters
Drain the cucumbers and peppers fully before adding the brine. Salted vegetables hold a lot of water. If they are not well drained, that water dilutes the vinegar brine, weakening its acidity and flavour and leaving the pickles soft and watery.
Swap the ginger
How well each one fits the dish's main ingredients (cucumber, pepper, cider, vinegar, turmeric, mustard, horseradish):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Gingerthe original
