Why it works: Tomato and celery are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Prepare the jelly
Dissolve the gelatin in cold water.
Add the stewed tomatoes and season with sugar, salt, pepper, celery salt, and onion.

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 as it cools.
- Stewed tomatoes
- Provide the main flavor, body, and liquid of the jelly.
- Sugar
- Balances the acidity of the tomatoes with sweetness.
The step that matters
Dissolve the gelatin in cold water. Gelatin must be fully dissolved before the tomatoes are added, otherwise it will not disperse evenly and may set in lumps or fail to set firmly. Cold water lets it hydrate first before the mixture is heated.
Swap the onion
How well each one fits the dish's main ingredients (gelatin, tomato, sugar, pepper, celery):
- Capsicumfits better
- Carrotfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against gelatin, tomato, sugar, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
