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

What each ingredient does

Cucumbers: Provide the main body and crisp, fresh flavour that the vinegar draws out and carries.
Vinegar: Acts as the solvent and preservative, extracting flavour from the cucumbers and keeping the liquid stable.
Shallots: Add a mild onion-like sharpness and aroma that mellows during the long steep.
Garlic: Adds pungent aroma that softens and blends into the vinegar over time.
