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 ↓
Spanish Pickle
Ingredients
Directions
Prepare the vegetables
Soak the cauliflower in salt water overnight.
Chop the green tomatoes, onions, and mango peppers separately, sprinkle with salt, and drain overnight.
In the morning, chop twice the amount of cabbage as you have tomatoes and mix with the drained vegetables.
Add the cucumber pickles, cutting some round and some lengthwise.
Season and cover
Mix in the white mustard seed, celery seed, turmeric, and grated horseradish.
Add enough vinegar to cover the mixture, adjusting with water if the vinegar is very sour, and sweeten to taste.
If desired, add fresh celery cut into squares or diamonds.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the pickle and release moisture that the salting draws out.
- Cabbage
- Adds crisp texture and body to the mixture.
- Cucumber pickles
- Add tang and a firm, crunchy bite to the mix.
- White mustard seed
- Contributes sharp, pungent flavour that mellows in the vinegar.
- Horseradish
- Adds pungent heat that fades during pickling.
- Vinegar
- Acidity that preserves the vegetables and gives the pickle its sharp taste.
The step that matters
Salting and draining the vegetables overnight. Salt draws water out of the tomatoes, onions, and peppers by osmosis. Draining well removes that liquid, so the finished pickle stays crisp rather than watery and diluted in the vinegar.
Swap the mango
How well each one fits the dish's main ingredients (cauliflower, tomato, onion, pepper, cabbage, cucumber, mustard):
- Avocadofits better
- Limefits better
- Lemonfits about as well
- Mangothe original
Fit is the average pairing score against cauliflower, tomato, onion, pepper, cabbage, cucumber, mustard. Candidates are from the same food group and used in at least 100 recipes.
