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 ↓
Mixed Mustard Pickles
Ingredients
Directions
Prepare the vegetables
Cover onions, cucumbers, and cauliflower with strong brine and let sit overnight.
In the morning, pour off the brine and drain the pickles well.
Make the dressing

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sweet-sour mixture into a smooth, spoonable sauce.
- Egg
- Adds richness and helps thicken the dressing as it cooks.
- Mustard
- Adds sharp, pungent flavor that balances the sweetness of the sugar.
- Brown sugar
- Sweetens the vinegar and softens the sharpness of the pickling liquid.
- Vinegar
- Acidifies the mixture, preserving the vegetables and giving them tang.
The step that matters
Stir the mixture into the hot vinegar and cook. Flour and egg thicken only when heated, but they can clump or scramble if added to cold liquid or boiled too hard. Stir constantly while cooking so the dressing turns smooth and even.
