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 flavour and a fresh, mild vegetable character as they steep.
- Onions
- Add savoury depth and pungency that mellows during the rest period.
- Vinegar
- Acts as the solvent and preserving base, drawing flavour out of the vegetables and aromatics.
- Shallots
- Contribute a mild onion-like sweetness and aroma to the infusion.
- Garlic
- Adds pungent aroma that softens and mellows as it infuses in the vinegar.
The step that matters
Let it stand for 4 days. Flavour is extracted slowly by the acid over time. Stopping early leaves the vinegar weak and harsh, so the full standing time matters.
