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 cucumbers, green tomatoes, onions, cauliflower, and bell peppers in a large container.
Prepare brine by dissolving 1 cup of coarse salt in 1 gallon of water.
Cover the vegetables with the brine.
Let the mixture sit for 24 hours.
Make the mustard sauce and combine
Scald the mixture in the brine and drain.
In a bowl, make a paste with ground mustard, flour, sugar, and enough vinegar to dissolve.
Add the paste to 2 quarts of boiling vinegar.
Let the mixture thicken.
Add the drained pickles to the thickened mixture. Stir to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the pickle and stay crisp-textured after brining.
- Cauliflower
- Adds firm, crunchy florets that hold their shape in the thick sauce.
- Ground mustard
- Provides the pungent, sharp flavor that defines the pickle and thickens the sauce.
- Flour
- Thickens the mustard paste so it coats the vegetables evenly.
- Vinegar
- Provides acidity that preserves the pickles and gives them their tang.
- Sugar
- Balances the sharpness of the vinegar and mustard with sweetness.
The step that matters
Adding the paste to boiling vinegar. The mustard and flour paste must be smoothly dissolved before it meets the hot vinegar; otherwise lumps form and the sauce thickens unevenly. Keeping the vinegar at a full boil ensures the flour starch swells and thickens properly.
Swap the onion

Fit is the average pairing score against cucumber, tomato, cauliflower, pepper, mustard, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
