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.
