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.

Swap the tarragon

How well each one fits the dish's main ingredients (vinegar, cider):
