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 ↓
Tomato Jelly
Ingredients
Directions
Make the jelly
Boil the soup stock, tomatoes, onion, clove, peppercorns, salt, sugar, and ketchup together for 30 minutes or until the tomatoes are soft.
Soften the gelatin in ½ cup of cold water, then stir it into the tomato mixture until dissolved.
Mold the mixture in a ring mold or cup.
Serve
Serve with celery salad mixed with mayonnaise or a cooked dressing in the center, surrounded by lettuce.

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, sliceable jelly when chilled.
- Tomatoes
- Provide the main body, acidity and flavor of the jelly.
- Soup stock
- Adds savory depth as the liquid base of the jelly.
- Sugar
- Balances the acidity of the tomatoes and rounds out the flavor.
The step that matters
Dissolving the gelatin. Gelatin must be softened in cold water first, then fully dissolved into the hot tomato mixture. Undissolved granules leave gritty spots, and the jelly will not set evenly if the gelatin is not completely melted before molding.
Swap the onion
How well each one fits the dish's main ingredients (tomato, clove, sugar, ketchup, gelatin):
- Capsicumfits better
- Carrotfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against tomato, clove, sugar, ketchup, gelatin. Candidates are from the same food group and used in at least 100 recipes.
