Why it works: Tomato and corn match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,099 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Tomato- Jelly
Ingredients
Directions
Stew the tomatoes with salt and pepper until soft.
Strain the pulp through a fine sieve or jelly bag.
Add ½ cup white sugar and 1 tablespoon corn-starch dissolved in ½ cup cold water to the strained tomato.
Heat the mixture over the fire, stirring until it boils for one minute.
Cool the jelly before serving with meats.

Pepper and sugar barely smell alike, yet cooks put them together in 19,401 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and flavor of the jelly once stewed and strained.
- Corn-starch
- Thickens the strained tomato liquid into a jelly when heated and boiled.
- White sugar
- Adds sweetness that balances the acidity of the tomatoes.
The step that matters
Boil the mixture for one minute while stirring. Cornstarch only thickens fully once it reaches a boil and its granules swell and gelatinize. Stirring prevents scorching and lumps, and a full minute at the boil ensures the starch sets the jelly.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, sugar, corn):
- Capsicumfits better
- Carrotfits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against pepper, sugar, corn. Candidates are from the same food group and used in at least 100 recipes.
