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 ↓
Oil Cucumbers
Ingredients
Directions
Prepare
Slice cucumbers thinly, layer them in a jar, sprinkling with ½ pint of coarse sea salt, and let them sit overnight or for 1–2 days.
Drain the water.
Layer and pack
Add a thin layer of cucumber slices, 2 thin onion slices, a little red pepper, a blade of mace, a sprinkle of mustard seed, white pepper, and celery seed, and 2 tablespoons of oil.
Repeat the layering process until the jar is full, finishing with best vinegar.
Cure
Let the pickles sit for 2 months before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp body of the pickle, which salt draws water out of before layering.
- Coarse sea salt
- Draws water out of the cucumbers, firming them and helping preserve the pickle.
- White mustard seed
- Adds a sharp, pungent flavour that mellows during the long rest.
- Best vinegar
- Adds acidity that sharpens the flavour and helps preserve the jar.
- Best salad oil
- Adds fat and a mild richness that coats the cucumber layers.
The step that matters
Draining after the salt rest. Cucumbers release a lot of water under salt. If the water is not fully drained before layering, the pickles will be diluted and may lose crispness and flavour.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, mustard, celery, mace, onion, pepper, vinegar):
- Tarragonfits better
- Dillfits better
- Allspicefits better
- White pepperthe original
Fit is the average pairing score against cucumber, mustard, celery, mace, onion, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
