Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the tomato liquid into a firm, sliceable jelly as it cools.
- Strained tomatoes
- Provide the main liquid, body and tomato flavour of the jelly.
- Lemon juice
- Adds acidity that brightens the tomato flavour and balances its sweetness.
The step that matters
Adding the soaked gelatin. Gelatin must be fully dissolved in the hot tomato mixture before straining and molding. Undissolved granules leave a grainy texture, and the jelly sets only once the gelatin is evenly distributed and the mixture cools.
Swap the onion
How well each one fits the dish's main ingredients (gelatin, tomato, celery, lemon):
- Carrotfits better
- Capsicumfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against gelatin, tomato, celery, lemon. Candidates are from the same food group and used in at least 100 recipes.
