Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and hold the other ingredients together.
- Sardines
- Provide the main protein and a rich, savory flavor.
- Egg yolks
- Mashed into the dressing to add richness and a smooth, creamy body.
- Olive oil
- Adds fat to the dressing, carrying flavor and giving it a silky texture.
- Vinegar
- Adds acidity that brightens the flavor and balances the oily fish.
The step that matters
Dressing the salad with gentle tossing. Potatoes and fish break apart easily, so folding the dressing in gently keeps the pieces intact while still coating them evenly.
Flavor stand-ins for the cabbage
How well each one fits the dish's main ingredients (potato, pepper, egg, olive, vinegar, onion, parsley):

- Cabbagethe original
Fit is the average pairing score against potato, pepper, egg, olive, vinegar, onion, parsley. 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
