Why it works: Green beans and beans share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 36 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cabbage
Forms the bulk of the relish and gives it a crisp, sturdy texture.
Cucumbers
Adds crunch and fresh moisture that stays firm during pickling.
Sugar
Balances the sharpness of the vinegar and adds sweetness.
Cider vinegar
Provides the acidity that preserves the vegetables and gives the pickle its tang.
Mustard seed
Contributes a sharp, pungent flavor that deepens as the relish sits.
Ground mustard
Adds pungency and warmth that spreads through the vinegar brine.

The step that matters

Sealing the jars after the flavors meld. Vinegar acidity protects the relish only when the jars are sealed tightly, keeping air and spoilage microbes out while the vegetables cure.
