Why it works: Celery and lettuce match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 2,033 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓
Tomato Jelly Salad
Ingredients
Directions
Prepare the gelatin and tomatoes
Soak the gelatin in ½ cup of cold water for 15 minutes.
Season the tomatoes, boil, and strain, adding hot water to make 3 cups.
Dissolve the gelatin in the boiling tomato mixture.
Mold and serve
Pour into two molds of different sizes to create a cup-like shape.
Once cold, unmold onto lettuce leaves.
Fill with mixed and marinated celery and pecan meats, then cover with mayonnaise.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the tomato liquid into a firm jelly that holds the cup shape when unmolded.
- Tomatoes
- Provide the main flavour and liquid base of the jelly, giving it acidity and colour.
- Mayonnaise
- Adds fat and creaminess that contrasts with the tart jelly and crisp vegetables.
- Celery
- Adds crisp texture and a fresh, mildly savoury crunch to the filling.
- Pecan meats
- Add crunchy texture and a rich, nutty flavour to the filling.
The step that matters
Dissolve the gelatin in the boiling tomato mixture. Gelatin must fully dissolve in hot liquid to set evenly; undissolved granules leave soft spots or grainy patches in the jelly. Cooling the mixture before molding lets it set firmly.

Fit is the average pairing score against gelatin, tomato, celery, meat. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
