Why it works: Fish and lettuce work together. They rank in the top 18% of all ingredient pairs, and cooks put them together in 196 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Jellied Fish
Ingredients
Directions
Prepare the fish
Boil the fish in salted water until cooked through.
Carefully remove the skin and bones, preserving the shape of the fish.
Place the fish on a platter with the head and tail intact, and sprinkle with whole peppers and bay leaves.
Set the aspic
Soak the gelatin for 1 hour, then pour over it 1 quart of hot fish stock.
Pour the gelatin mixture over the fish and set on ice.
Serve
When ready to serve, loosen the edges of the gelatin and place crisp lettuce leaves under and around the fish.
Serve with sauce tartar poured over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the fish stock into a firm, clear jelly that holds the fish in shape.
- Fish stock
- Carries the flavour of the fish and becomes the liquid that the gelatine sets.
- White fish
- Provides the main protein, which is cooked through and then set in the jelly.
The step that matters
Soaking the gelatine before adding hot stock. Gelatine must first hydrate in cool liquid so its strands separate; adding it dry or to very hot liquid can leave lumps and weaken the set.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, lettuce, sauce):
- Capersfits better
- Tarragonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against fish, lettuce, sauce. Candidates are from the same food group and used in at least 100 recipes.
