Why it works: Capers and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 372 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Jellied Fish
Ingredients
Directions
Prepare the jelly
Mix the fish and capers and place them in a mold.
Soak the gelatin in cold water, then add boiling water and stir until dissolved.
Add lemon juice and salt to the gelatin mixture.
Set and serve
Pour the jelly carefully over the fish and refrigerate until set.
Optionally, add sliced celery or hard cooked eggs to the fish.
Cut into portions and serve on lettuce with salad dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a firm, sliceable jelly around the fish.
- Fish
- Forms the main body of the dish, held in place by the set jelly.
- Lemon juice
- Adds acidity that brightens the flavor of the jelly and fish.
The step that matters
Pour the jelly carefully over the fish. Pouring too fast or from too high can disturb the fish and capers and trap air bubbles. Gelatin needs to be liquid but not hot enough to cook the fish, and it must set fully in the refrigerator for clean portions.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (lemon, gelatin, fish, capers, lettuce, egg):
- Tarragonfits better
- Parsleyfits better
- Dillfits about as well
- Celerythe original
Fit is the average pairing score against lemon, gelatin, fish, capers, lettuce, egg. Candidates are from the same food group and used in at least 100 recipes.
