Why it works: Mustard and celery 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 ↓
Sour Pickles
Ingredients
Directions
Make the brine
Boil the cider vinegar, water, brown sugar, and coarse sea salt for ten minutes, then skim well.
When the mixture is cold, make a smooth paste with the ground mustard and a little of the boiled vinegar.
Mix the mustard paste with the remaining vinegar mixture and pour it into a jar.
Add the pickles
Wash and dry enough medium-sized pickles to fill the jar, leaving space below the vinegar.
Sprinkle the pickles with celery and nasturtium seeds.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the sour acidity that defines the pickle and preserves the cucumbers.
- Brown sugar
- Balances the sharp acidity with sweetness and adds a molasses depth to the brine.
- Coarse sea salt
- Seasons the brine and helps draw flavour into the pickles.
- Ground mustard
- Adds pungent flavour and thickens the brine when mixed into a paste.
- Medium-sized pickles
- The vegetable being pickled, which absorbs the brine's acidity and sweetness.
The step that matters
Make the mustard paste while the mixture is cold. Mixing ground mustard into hot liquid can make it clump and turn bitter, so it should be blended into a smooth paste first and combined once the brine has cooled.
Swap the celery
How well each one fits the dish's main ingredients (cider, vinegar, sugar, mustard):
- Allspicefits better
- Tarragonfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against cider, vinegar, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
