Why it works: Vinegar and cider are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh tarragon leaves
- Provides the main aroma and flavour that the vinegar takes on during steeping.
- Vinegar
- Acts as the solvent that draws flavour out of the leaves and preserves the finished liquid.
- Isinglass
- Fining agent that binds suspended particles so they settle, leaving the vinegar clear.
The step that matters
Transfer to a clean jar and let it sit until clear. Fining needs time to work. Isinglass gathers suspended particles and drags them down, so rushing this step or disturbing the jar leaves the vinegar cloudy.
