Why it works: Cucumber and watercress match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 140 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Maquereau Marine Aux Olives
Ingredients
Directions
Poach the fish
Boil the mackerel in equal parts water and vinegar until cooked.
Remove the fish and place it in a deep dish, pouring the cooking liquid over it.
Refrigerate overnight.
Serve
For serving, carefully remove the fillets from the fish and place them on a dish over ice.
Cover the fillets with mayonnaise sauce and garnish with chopped olives.
Arrange turned olives, cold cucumber fillets, and watercress around the dish, adding aspic jelly if available.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main flesh of the dish, cooked gently in the vinegar liquid.
- Vinegar
- Acidity in the poaching liquid that sharpens the flavour of the fish.
- Mayonnaise sauce
- Adds richness and fat that coats the cold fillets.
- Aspic jelly
- Sets into a clear jelly that holds the garnish in place and adds gloss.
The step that matters
Refrigerate overnight. Chilling the fish slowly in its cooking liquid lets it firm up and absorb acidity, so the fillets hold together when lifted out and served cold.
Swap the cucumber
How well each one fits the dish's main ingredients (vinegar, sauce, olive, watercress):
- Horseradishfits better
- Mustardfits better
- Shallotfits better
- Cucumberthe original
Fit is the average pairing score against vinegar, sauce, olive, watercress. Candidates are from the same food group and used in at least 100 recipes.
