Why it works: Celery and mustard 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 ↓

Sprinkle with coarse sea salt and let sit for 24 hours.

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 pickle and stay crisp-textured once salted and drained.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming them before they are pickled.
- Cold vinegar
- Provides the sharp acidity that preserves and flavours the pickle.
- Onions
- Add sharpness and aroma that mellow as they sit in the brine.
The step that matters
Draining the salt off before layering. Salt draws water out of the cucumbers and onions. Draining and rinsing off the excess keeps the pickle from tasting overly salty, while the vegetables stay firm.
Swap the mace
