Why it works: Cucumber and green beans share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 95 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mustard Pickle
Ingredients
Directions
The book gives no oven temperature. The 180°F (82°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the vegetables
Cut all vegetables before measuring: slice cucumbers, halve tomatoes, cut green beans into 1‑inch lengths, and chop peppers.
Soak all vegetables in brine overnight, then rinse in clear water for 2 hours.
Let the vegetables stand in a mixture of 1 part vinegar and 1 part water for 15 minutes, then scald in the same liquid.
Make the dressing
Mix the dry ingredients until smooth, then gradually add hot vinegar while stirring to form a smooth paste.
Cook the dressing over a pan of water, stirring carefully until it thickens.
Pack and process
Drain the vegetables thoroughly and pour the hot mustard dressing over them, mixing well.
Pack the mixture into sterilized jars and process in a water bath at 180°F (82°C) for 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the mustard dressing so it becomes a smooth, coating paste.
- Powdered mustard
- Supplies the sharp, pungent flavour that defines the pickle.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Provides acidity that preserves the vegetables and sharpens the flavour.
- Turmeric
- Gives the pickle its characteristic yellow colour.
The step that matters
Cooking the dressing until it thickens. Flour thickens only when heated enough for its starch to swell, so stirring steadily over gentle heat prevents lumps and scorching while the dressing sets smooth.
Swap the green beans
How well each one fits the dish's main ingredients (cucumber, onion, pepper, fig, vinegar, flour, sugar):
- Capsicumfits better
- Mustardfits better
- Beetrootfits better
- Green beansthe original
Fit is the average pairing score against cucumber, onion, pepper, fig, vinegar, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
