Why it works: Fish and olive match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 216 recipes mention both. Both carry 2-undecenal, which smells sweet. The science ↓
The recipe
Ingredients
Contains: egg, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the terrine
Season the fish well and boil it until it can be pulled apart into small pieces.
In a mold, layer the fish, beets, olives, and capers until full.
Make the gelatine broth
Soak the gelatine in enough cold water to dissolve it.
Pour the hot fish broth over the gelatine until dissolved.
Pour the broth into the mold over the layers until it is full.
Serve
Once cold, remove from the mold and serve on lettuce with mayonnaise dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large fish
- Forms the main body of the terrine, set firmly in the gelatine.
- Gelatine
- Sets the broth into a firm jelly that holds the layers together when sliced.
- Beets
- Adds colour and an earthy sweetness to the layers.
- Olives
- Adds salty, briny flavour that contrasts with the fish.
- Capers
- Adds sharp, acidic bite that cuts through the rich fish and mayonnaise.
- Fish broth
- Carries flavour into the gelatine and fills the spaces between the layers.
The step that matters
Soak the gelatine before dissolving it. Gelatine must hydrate in cold water before hot broth is added, so it dissolves evenly. Adding it dry or to hot liquid can leave clumps and weaken the set.
Flavor stand-ins for the lettuce

Fit is the average pairing score against fish, 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).
