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

What each ingredient does

Vinegar: Provides the sharp acidity that defines this piquant sauce.
Shallot: Adds a mild, sharp onion flavour that softens as the sauce stands.
Capers: Contribute briny, tangy notes that add punch to the sauce.
Pickles: Add tart, sour flavour and a bit of crunch.

Fit is the average pairing score against vinegar, shallot. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
