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
- Tarragon leaves
- Supply the aromatic flavor that the vinegar takes up during infusion.
- Vinegar
- Acts as the solvent that extracts flavor from the tarragon leaves.
- Isinglass
- Fining agent that binds haze particles so they settle out, leaving the vinegar clear.
The step that matters
Letting the mixture sit until clear. Isinglass must be fully dissolved and given time to settle. Rushing this step leaves haze in the vinegar, because the fining agent needs time to bind suspended particles and carry them to the bottom.
