Why it works: Radish and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 297 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
French Beans
Ingredients
Directions
Prepare the beans
Gather young white runner beans before they are half-grown.
Prepare a hot brine and soak the beans in it for 1–2 days, depending on desired flavor.
Drain the beans and let them dry completely.
Pickle
Place the beans in clean, dry jars and cover with hot vinegar pickling solution.
For each quart of vinegar, add 1 ounce each of horse-radish, black pepper, allspice, and mustard seed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White runner beans
- The main vegetable, whose firm texture is kept through the brine and vinegar.
- Coarse sea salt
- Draws water out of the beans and seasons them during the brine soak.
- Vinegar
- Acidity that preserves the beans and gives the pickle its sharp, tangy flavor.
- Horse-radish
- Adds a sharp, pungent heat that infuses into the vinegar.
- Mustard seed
- Contributes a sharp, pungent flavor as it steeps in the vinegar.
- Allspice
- Adds warm, aromatic spice notes to the pickling solution.
The step that matters
Drain the beans and let them dry completely. Surface water left on the beans dilutes the hot vinegar, weakening its acidity and flavor, so the pickle may spoil or taste watery.
