Why it works: Tomato and lettuce are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,655 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Jellied Tomato
Ingredients
Directions
Make the jelly
Boil the onion in the tomato juice until soft, then let it stand overnight.
The next morning, dissolve the gelatine in ½ cup of water.
Bring the tomato and onion mixture to a boil, then pour it over the dissolved gelatine.
Season with coarse sea salt and pour into molds.
Serve
Once set, turn out onto lettuce leaves and fill the center with mayonnaise dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato juice
- Forms the main body and flavour of the jelly.
- Gelatine
- Sets the liquid into a firm, sliceable jelly.
- Onion
- Adds savoury depth to the tomato juice as it steeps.
- Mayonnaise dressing
- Adds richness and creamy contrast to the tangy jelly.
The step that matters
Dissolve the gelatine fully before combining. Gelatine only sets when fully dissolved and evenly mixed into the liquid. Undissolved granules leave weak or grainy spots, so the jelly may not hold its shape when turned out.
Swap the onion
How well each one fits the dish's main ingredients (tomato, lettuce):
- Cucumberfits better
- Okrafits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against tomato, lettuce. Candidates are from the same food group and used in at least 100 recipes.
