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 Pickle
Ingredients
Directions
Prepare the vegetables
Combine cucumbers, green tomatoes, cauliflower, onions, and green peppers in a large bowl.
Make a brine with 4 quarts of water and 1 cup of coarse sea salt; pour over the vegetables and let soak for 24 hours.
Drain the vegetables and heat just enough to scald them.
Make the mustard sauce
In a separate bowl, mix flour, ground mustard, and turmeric with enough cold vinegar to make a smooth paste.
Add 1 cup of sugar and enough vinegar to bring the total to 2 quarts.
Heat the mixture, stirring constantly until it thickens.
Combine and finish
Add the vegetables and cook until heated through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the mustard sauce into a smooth, thick paste when heated.
- Ground mustard
- Provides the sharp, pungent flavor that defines the pickle.
- Turmeric
- Gives the pickles their characteristic yellow color.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Provides acidity that preserves the pickles and sharpens the flavor.
- Cauliflower
- Adds firm, crisp texture that holds up in the thick sauce.
The step that matters
Heat the mixture, stirring constantly until it thickens. Flour thickens only when heated, and it can scorch or form lumps on the bottom of the pan if left unstirred. Constant stirring keeps the sauce smooth and evenly thickened before the vegetables are added.
Swap the onion

- Lettucefits better
