Why it works: Olive and capers are a kitchen classic. They rank in the top 4% of all ingredient pairs, and 1,555 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickled herrings
- Provide the main fish flavour and a salty, tangy base for the salad.
- Potatoes
- Add body and starch that soak up the dressing and hold the salad together.
- Apple
- Adds crisp texture and mild sweetness to balance the sharp pickled flavours.
- Pickled beet
- Adds sweet-sour flavour and a deep colour to the salad.
- Oysters
- Add briny, delicate seafood flavour and a soft texture.
The step that matters
Dress the salad while the potatoes are still cold. Cold potatoes absorb the oil, vinegar, and seasoning less readily than warm ones, so the dressing can pool rather than coat evenly. Toss gently so the slices stay intact and the dressing distributes through the whole bowl.

Fit is the average pairing score against potato, vinegar, pepper, oyster, olive, capers. 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).
