Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the tomato juice into a firm, sliceable jelly as it cools.
- Tomato juice
- Forms the liquid base and provides the savoury tomato flavour of the jelly.
- Hard boiled eggs
- Add protein-rich texture and a mild, creamy contrast to the tart jelly.
- Mayonnaise made with olive oil
- Adds richness and fat that balances the acidity of the tomato jelly.
The step that matters
Strain the boiled mixture into a mold. Gelatin must be fully dissolved before the mixture is poured and chilled. Straining removes any undissolved gelatin and bits, so the jelly sets smooth and clear rather than grainy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, gelatin, sauce, pepper, olive, egg, lettuce):
- Capsicumfits better
- Cucumberfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against tomato, gelatin, sauce, pepper, olive, egg, lettuce. Candidates are from the same food group and used in at least 100 recipes.
