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
Prepare the vegetables
Combine equal quantities of small cucumbers, button onions, cauliflower florets, sliced green tomatoes, and sliced green peppers.
Soak the vegetables in brine and then drain.
Make the mustard sauce
In a pot, combine 1 quart of vinegar and 1 cup of brown sugar. Boil for 5 minutes and skim off any foam.
Mix ½ cup of flour and ½ cup of ground mustard together. Slowly pour the hot vinegar mixture onto the flour and mustard, stirring until smooth.
Pour the hot mixture over the pickles.
Rest
Let the pickles sit for 3 weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflower
- Forms the firm, crunchy bulk of the pickle mix.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Flour
- Thickens the hot vinegar mixture into a smooth, cohesive sauce.
- Ground mustard
- Gives the sauce its sharp, pungent mustard flavour.
- Vinegar
- Provides the acidity that preserves and sharpens the pickles.
The step that matters
Stirring the hot vinegar into the flour and mustard. Flour lumps form if the liquid is added too fast or without constant stirring. Pouring slowly while stirring lets the starch hydrate evenly, giving a smooth sauce.
