Why it works: Cauliflower and cucumber 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 ↓
Sweet Vinegar Pickles
Ingredients
Directions
Prepare the vegetables
Soak the cauliflowers, onions, and cucumbers in saltwater for 24 hours.
Drain and scald them three times with boiling water for about 15 minutes each time.
Drain again and place in a crock.
Pickle
Cover with vinegar, water, brown sugar, and mixed spice.
Bring to a boil and pour over the pickles.
Leave the spice bag on top of the crock and cover firmly.
Let sit for about 6 weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sour acidity that defines the pickle and helps preserve the vegetables.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Cauliflowers
- Main vegetable that becomes firm and crisp-tender once brined and pickled.
- Cucumbers
- Main vegetable that stays crisp and absorbs the sweet-sour pickling liquid.
- Small yellow onions
- Main vegetable that softens slightly and takes on the sweet-sour flavor of the brine.
The step that matters
Scalding the vegetables three times. Repeated scalding in boiling water softens the vegetables gradually, so they pick up the pickling liquid without turning mushy. Draining well between scaldings matters because excess water dilutes the vinegar brine.
