Why it works: Cauliflower and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 687 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Mustard Pickles
Ingredients
Directions
Prepare the vegetables
Scald the small onions and cauliflower in salt water.
Sprinkle salt on the sliced green tomatoes and let them sit overnight.
In the morning, strain off the juice from the tomatoes.
Combine the small pickles and nasturtiums in a jar with the tomatoes.
Pour enough vinegar over the vegetables to cover them.
Make the mustard syrup
Measure the vinegar and pour it off into a pot.
For each quart of vinegar, add 1-2 cups of brown sugar, ¼ pound of ground mustard, and 1 tablespoon of flour.
Mix the flour and mustard smoothly with cold vinegar.
Pour the mixture into the hot vinegar.
Once the flour is cooked, pour the mixture hot over the pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Supply the bulk of the pickle and, after salting, release juice that is drained off before pickling.
- Ground mustard
- Gives the pickling liquid its sharp, pungent mustard flavour.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar and mustard.
- Flour
- Thickens the hot vinegar mixture so it coats the vegetables rather than running off.
- Vinegar
- Acidic base that preserves the vegetables and carries the mustard and sugar flavours.
The step that matters
Mixing the flour and mustard smoothly with cold vinegar before adding it to the hot vinegar. Flour and ground mustard clump when added dry or to hot liquid. Blending them into cold vinegar first keeps the particles separate, so the mixture thickens evenly once heated and cooked through.
Swap the onion
How well each one fits the dish's main ingredients (cauliflower, tomato, cherry, pepper, vinegar, sugar, mustard):
- Cucumberfits better
- Capsicumfits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against cauliflower, tomato, cherry, pepper, vinegar, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
