Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Tomato Jelly Salad
Ingredients
Directions
Prepare
Soak the box of gelatin in cold water.
In a saucepan, combine the canned tomatoes, whole dry pepper, sliced onion, chopped parsley, chopped celery, and salt to taste.
Cook until the onion is tender, then push the mixture through a strainer.
Make the jelly
Bring the strained mixture to a boil and pour it over the gelatin; beat well.
Pour the mixture into small molds and cool.
Serve
Serve the jelly on lettuce leaves with mayonnaise.
Make sandwiches with rye bread and Swiss cheese, toast them in the oven, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the strained tomato liquid into a firm, sliceable jelly.
- Canned tomatoes
- Provide the main body, acidity and flavor of the jelly.
- Onion
- Adds savory aroma and depth to the tomato base.
- Swiss cheese
- Adds melting fat and savory flavor to the sandwiches.
The step that matters
Pour the boiling mixture into the gelatin and beat well. Gelatin must fully dissolve in hot liquid to set evenly. Undissolved granules or a lukewarm mixture can leave lumps or a weak, uneven set once cooled.
Swap the onion
How well each one fits the dish's main ingredients (gelatin, tomato, pepper, parsley, celery, lettuce, rye):
- Carrotfits better
- Beetrootfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against gelatin, tomato, pepper, parsley, celery, lettuce, rye. Candidates are from the same food group and used in at least 100 recipes.
