Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Jelly Salad
Ingredients
Directions
Make the jelly
In a pot, combine the tomato soup with an equal amount of hot water, salt, pepper, and sugar, then bring to a boil.
Soak the gelatine in the cold water for 30 minutes, then stir it into the hot soup until dissolved.
Pour the mixture into small individual molds that have been rinsed with cold water.
Serve
Once set, unmold the jelly onto nests of lettuce leaves.
Serve with salad cream or mayonnaise.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the hot tomato liquid into a firm, sliceable jelly as it cools.
- Tomato soup
- Forms the base of the jelly, giving its main flavour and colour.
- Sugar
- Adds mild sweetness that balances the acidity of the tomato.
The step that matters
Dissolve the gelatine completely in the hot soup. Gelatine only sets properly when it is fully dissolved and evenly distributed. Stirring it into the hot soup until no grains remain gives a smooth, uniform jelly. Undissolved gelatine can leave a grainy texture or weak spots in the set.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, sugar, cream):
- Capsicumfits better
- Spinachfits better
- Mustardfits better
- Tomatothe original
Fit is the average pairing score against pepper, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
