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 ↓
Mustard Pickles
Ingredients
Directions
Brine the vegetables
Combine the green peppers, small onions, small cucumbers, pickled cauliflowers, and sliced cucumbers in a large container.
Mix 1 tablespoon of coarse sea salt with 1 quart of water to create a brine, then pour it over the vegetables until they are fully covered.
Let the mixture stand for 24 hours, then drain off the brine.
Make the dressing
In a pot, combine 1 gallon of vinegar, 6 tablespoons of mustard, 1½ cups of brown sugar, ½ cup of flour, ½ ounce of turmeric, and ½ ounce of curry powder.
Boil the dressing for 5 minutes, stirring constantly until thickened.
Pour the hot dressing over the pickles and ensure it has the consistency of thick sour cream.
If the dressing is not thick enough, add more flour and boil again.
Store
Store the pickles in crocks, covered tightly with thick paper.

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 preserves the vegetables and sharpens the flavour.
- Flour
- Thickens the dressing so it coats the vegetables rather than running off.
- Brown sugar
- Adds sweetness that balances the sharp vinegar and mustard.
- Mustard
- Contributes the sharp, pungent mustard flavour of the dressing.
- Turmeric
- Gives the dressing its bright yellow colour and earthy flavour.
- Curry powder
- Adds warm spice aroma to the dressing.
The step that matters
Boiling the dressing until thickened. Flour thickens only when its starch is heated with liquid long enough to swell and gel. Stirring constantly prevents scorching on the bottom of the pot, and a dressing that is too thin will not cling to the pickles.
