Why it works: Cinnamon and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Tomato Jelly
Ingredients
Directions
Make the tomato base
In a pot, combine the tomatoes, cinnamon, cloves, onion, vinegar, bay leaf, salt, and pepper.
Cook until the tomatoes are dissolved.
Pass the mixture through a sieve to remove solids.
Set and serve
Soak the gelatine in water for a few minutes, then add it to the hot tomato mixture.
Pour the liquid into small moulds or jelly glasses, filling them halfway.
Set the moulds on ice to chill and set.
Serve on a lettuce leaf with mayonnaise dressing.

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 flavour of the jelly, and most of its liquid.
- Knox's gelatine
- Forms a network that sets the strained tomato liquid into a firm jelly when chilled.
- Onion
- Adds savoury depth to the tomato base as it cooks down.
- Vinegar
- Adds acidity that brightens the tomato flavour.
The step that matters
Adding the gelatine to the hot tomato mixture. Gelatine must be fully softened and then dissolved in the hot liquid; if it is not fully dissolved or the mixture is too hot, it will not set properly, and if it cools too much before pouring, it can set unevenly in the moulds.
Swap the onion
How well each one fits the dish's main ingredients (tomato, cinnamon, clove, vinegar, pepper):
- Capsicumfits better
- Carrotfits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against tomato, cinnamon, clove, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
