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

What each ingredient does

Cucumbers
Provide the bulk of the flavoring, releasing their juices into the vinegar as it stands.
Onions
Add pungency and savoury depth that mellows during the standing period.
Shallots
Contribute a mild, sweet onion flavor that blends into the vinegar.
Garlic
Adds sharp aroma and pungency that infuses into the vinegar.
Vinegar
Acts as the liquid base that extracts and preserves the flavors of the vegetables.

The step that matters

Letting the mixture stand for 4 days. The vinegar needs time to draw flavor out of the sliced vegetables and spices. Too short a steep leaves the vinegar weak and unbalanced, while the vegetables are needed to stay submerged so they do not spoil at the surface.
