Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the vegetables
Take fifty small pickles, two quarts of silver onions, two quarts of green string beans, one dozen green tomatoes, three heads of cauliflower; let the onions stand in brine for twelve hours, then peel.
If the beans are large, break them.
Slice the green tomatoes and cut up the cauliflower; let all stand in brine for twenty-four hours.
Make the mustard sauce
To one gallon of vinegar, use one pound of mustard (common is the best), mix it with a little vinegar, and add it to the rest.
Add one or two tablespoonfuls of oil of mustard and one tablespoonful of cayenne pepper; use more spices if preferred.
Tie the spices in a white cloth, and boil in the vinegar before adding the mustard.
Pack and seal
It can be put in pickle jars in alternate layers; fill three-quarters full; when filling the jars add here and there a little red and green pepper; fill up with the mustard; make air-tight.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Silver onions
- Firm vegetables that hold their crunch and add bulk to the pickle.
- Green string beans
- Provide crisp texture that softens only slightly in the brine and vinegar.
- Cauliflower (in the method)
- Adds firm, crisp pieces that absorb the mustard sauce's flavour.
- Green tomatoes
- Add tartness and firm texture that holds up to the vinegar.
- Mustard
- Gives the sauce its characteristic sharp, pungent flavour and thickens the vinegar.
The step that matters
Salting the vegetables in brine. Soaking the onions, tomatoes and cauliflower in brine draws out water, which keeps the pickle crisp and stops it from diluting the sauce.
Swap the onion
How well each one fits the dish's main ingredients (beans, vinegar, mustard, pepper, tomato):
- Capsicumfits better
- Lettucefits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against beans, vinegar, mustard, pepper, tomato. Candidates are from the same food group and used in at least 100 recipes.
