Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Jelly
Ingredients
Directions
Prepare
Soak the gelatine in cold water.
Rub the canned tomatoes through a colander.
Flavor the tomatoes with salt, cayenne pepper, celery salt, and a bay leaf.
Make the jelly
Add the flavored tomatoes to the soaked gelatine and heat until boiling.
Remove from heat and stir in Worcestershire sauce.
When the mixture is cool and starting to set, pour it into moulds lined with cucumber slices.
Serve
Turn out the jelly and serve garnished with lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the tomato liquid into a firm, sliceable jelly as it cools.
- Canned tomatoes
- Provide the main body, acidity and flavor of the jelly.
- Worcestershire sauce
- Adds savory, tangy depth to the tomato base.
The step that matters
Pour the jelly only when it is cool and starting to set. Gelatine sets as it cools. If the mixture is still hot, the mould may not hold its shape, and if it has set too far, the layers may not blend or pour cleanly into the cucumber-lined moulds.
Swap the celery
How well each one fits the dish's main ingredients (tomato, pepper, sauce, cucumber, lettuce):
- Tarragonfits better
- Capersfits better
- Corianderfits about as well
- Celerythe original
Fit is the average pairing score against tomato, pepper, sauce, cucumber, lettuce. Candidates are from the same food group and used in at least 100 recipes.
