Why it works: Cucumber and cauliflower match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 584 recipes. Both carry 2-hexenal, which smells green, leafy. The science ↓
Chow-chow, with Mustard Paste
Ingredients
Directions
Prepare the vegetables
Combine large cucumbers, small cucumbers, onions, green tomatoes, green peppers, cauliflower, and celery in a bowl.
Soak the vegetables in salt brine overnight.
Cook the relish
In the morning, drain the vegetables and mix them with mustard paste.
Cook the mixture slightly.
In a pot, boil the cider vinegar with yellow mustard, mustard seed, white sugar, turmeric, and celery seed for 5 minutes.
Add the vegetables to the pot and cook until tender, about 1 hour or longer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the sharp acidity that gives the relish its tang and helps preserve it.
- White sugar
- Balances the sharpness of the vinegar with sweetness.
- Mustard seed
- Adds a pungent, sharp flavour that defines the relish.
- Cucumbers
- Brining draws out water so they keep some firmness before the long cook.
- Cauliflower
- Holds its shape as a firm, chunky vegetable base that softens during cooking.
- Turmeric
- Gives the relish its bright yellow colour.
The step that matters
Cooking the vegetables in the vinegar until tender. Vegetables cooked in hot, acidic vinegar soften gradually. Stopping too early leaves them raw and crisp, while cooking too long turns them mushy and dulls their texture.
