Why it works: Sugar and gelatin are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Jellied Tomatoes
Ingredients
Directions
Make the tomato base
Combine the strained tomatoes, sugar, and finely chopped onion in a saucepan and boil for 10 minutes.
Add the white pepper, paprika, and salt, then strain the mixture through a fine strainer.
Soak the gelatin in 1 tablespoon of cold water, then add it to the hot tomato mixture.
Set and serve
Pour the mixture into small cups that have been rinsed in cold water.
Once firm, turn out the jellied tomatoes onto shredded lettuce.
Sprinkle with chopped parsley and serve with salad dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Strained tomatoes
- Provide the main body and flavour of the jelly.
- Gelatin
- Sets the tomato liquid into a firm, sliceable jelly when chilled.
- Onion
- Adds a savoury, aromatic background to the tomato base.
- Sugar
- Balances the acidity of the tomatoes.
The step that matters
Adding the gelatin to the hot mixture. Gelatin must be fully softened in cold water first, then dissolved into the hot tomato mixture. Added undissolved or lumpy, it sets unevenly and leaves a grainy texture in the finished jelly.
Swap the white pepper
How well each one fits the dish's main ingredients (tomato, onion, sugar, gelatin):
- Garlicfits better
- Celeryfits better
- Cinnamonfits better
- White pepperthe original
Fit is the average pairing score against tomato, onion, sugar, gelatin. Candidates are from the same food group and used in at least 100 recipes.
