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
Layer the cucumbers, tomatoes, onions, cauliflowers, and green peppers in a bowl with salt and let sit overnight.
In the morning, drain the vegetables and heat them in a mixture of 2 parts water and 1 part vinegar until scalding.
Drain again and set aside.
Make the mustard sauce
In a pot, mix the flour, ground mustard, sugar, and vinegar, then boil while stirring until thick and smooth.
Add the vegetables to the pot 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
- Cucumbers
- Their firm flesh holds shape and gives the pickles a crisp bite after brining.
- Flour
- Thickens the mustard sauce so it coats the vegetables instead of running off.
- Ground mustard
- Supplies the sharp, pungent flavour that defines the pickle.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Provides the acidity that preserves the vegetables and sharpens the flavour.
- Green tomatoes
- Add tart body and hold their shape in the thick sauce.
The step that matters
Boil the mustard sauce while stirring. Flour thickens only when it boils with liquid, and stirring prevents lumps from forming on the bottom of the pot. Stop too early and the sauce stays thin and grainy.
Swap the onion
