Why it works: Capers and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Swedish Salad
Ingredients
Directions
Prepare the fish
Wash, trim, and soak the mackerel in cold water for 1 hour.
Cover the mackerel with boiling water and simmer for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Provides the main flaky, meaty body of the salad after poaching.
- Roast beef
- Adds dense, savoury meat texture that holds its shape among the diced ingredients.
- Potatoes
- Add soft, starchy bulk that absorbs some dressing and binds the mixture.
- Hard-boiled eggs
- Contribute creamy richness and body to the salad.
- French salad dressing
- Supplies oil and acid that moisten the salad and carry the seasoning.
- Oysters
- Add briny, delicate flavour and a cold, soft texture as a topping.
The step that matters
Simmering the mackerel. Simmering gently keeps the fish moist and tender; boiling hard toughens the protein and breaks the flakes apart, so the fish should only just simmer.
