Why it works: Cinnamon and horseradish match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 515 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
Tomato Jelly
Ingredients
Directions
Make the jelly
Cook the tomatoes with cinnamon, onion, bay leaf, vinegar, salt, and pepper until soft.

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 flavor of the jelly.
- Gelatin
- Sets the tomato liquid into a firm, sliceable jelly.
- Whipped cream
- Adds richness and a soft, creamy texture to the sauce.
- Horseradish
- Adds sharp heat that contrasts with the sweet tomato.
The step that matters
Pour the hot tomato mixture over the dissolved gelatin. Gelatin must be fully dissolved and the tomato mixture hot enough to melt it evenly; otherwise lumps or uneven setting can result in the finished jelly.
Flavor stand-ins for the cinnamon
How well each one fits the dish's main ingredients (tomato, onion, vinegar, pepper, gelatin, horseradish, cream):
- Garlicbetter flavor fit
- Tarragonbetter flavor fit
- Celerybetter flavor fit
- Cinnamonthe original
Fit is the average pairing score against tomato, onion, vinegar, pepper, gelatin, horseradish, cream. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
