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, 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.
Pickle and rest
Pour the hot mixture over the pickles.
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
- Small cucumbers
- Form the bulk of the pickle and absorb the sauce as they rest.
- Cauliflower
- Adds firm texture that holds up through the long soak in vinegar.
- Flour
- Thickens the hot vinegar mixture into a smooth, coating sauce.
- Ground mustard
- Provides the sharp mustard flavour that defines the pickle.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Acidifies the sauce, providing tang and preserving the vegetables.
The step that matters
Stirring the vinegar into the flour and mustard. Pouring the hot liquid in slowly while stirring keeps the flour from clumping. Lumps form when flour meets hot liquid all at once, leaving the sauce grainy instead of smooth.
