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
Boil the tomatoes in water for 2-3 minutes, being careful not to overcook.
Pour boiling salt water over the vegetables and let them stand overnight.
Pickle
Afterward, pour hot vinegar over the mixture and let it sit for 2-3 days until pickled.
Make the dressing and serve
In a separate bowl, mix the flour and mustard well, then wet with a little cold vinegar.
Heat the vinegar and sugar together until boiling.
Add the flour and mustard mixture to the boiling vinegar and stir until thickened.
Pour the thickened mixture over the pickled vegetables.

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 so it coats the pickled vegetables.
- Dry mustard
- Adds sharp, pungent flavor that defines the pickle.
- Vinegar
- Provides acidity that preserves and sharpens the pickle.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Cucumbers
- Provide the crisp, firm body of the pickle.
The step that matters
Adding the flour and mustard mixture to the boiling vinegar. Flour thickens only when heated in liquid and stirred, so lumps can form if it is added unevenly. Mixing it smoothly with cold vinegar first helps it disperse before it gelatinizes into a uniform sauce.
