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 ↓

Ingredients
Directions
Prepare the mackerel
Wash, trim, and soak the mackerel in cold water for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Provides the main fish flavour and firm, flaky pieces that hold their shape in the salad.
- Boiled potatoes
- Adds bulk and a soft, starchy texture that absorbs some of the dressing.
- Hard-boiled eggs
- Adds richness and a soft, crumbly texture to the salad.
- French salad dressing
- Supplies oil and acidity that moisten the salad and carry its seasoning.
- Cold raw oysters
- Add a briny, delicate flavour and a soft, creamy texture as the topping.
The step that matters
Mixing the mackerel in carefully. Cooked fish flakes apart easily, so gentle folding keeps the pieces intact and the salad looking neat rather than mushy.
