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.
- Gelatine
- Sets the tomato liquid into a firm, sliceable jelly.
- Whipped cream
- Adds richness and a soft, mild texture to the sauce.
- Horseradish
- Contributes sharp, pungent heat to the sauce.
The step that matters
Dissolve the gelatine in cold water before adding the hot tomato mixture. Gelatine must be fully hydrated and dissolved before it meets the hot liquid. Undissolved granules can remain as lumps, and the jelly may set unevenly.
Swap the cinnamon
How well each one fits the dish's main ingredients (tomato, onion, vinegar, pepper, horseradish, cream):
- Garlicfits better
- Tarragonfits better
- Celeryfits better

Fit is the average pairing score against tomato, onion, vinegar, pepper, horseradish, cream. Candidates are from the same food group and used in at least 100 recipes.
