Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,058 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
Tomato Jelly
Ingredients
Directions
Make the tomato base
Boil the soup stock, tomatoes, sugar, ketchup, onion, garlic, salt, and peppercorns together for 30 minutes or until the tomatoes are soft.
Soften the gelatin in ½ cup of cold water.
Stir the softened gelatin into the tomato mixture until dissolved.
Set and serve
Pour the mixture into a mold.
Refrigerate until set.
Place the mold in warm water briefly.
Invert the jelly onto a serving dish.
Serve with celery salad mixed with mayonnaise or a cooked dressing in the center, surrounded by lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the tomato liquid into a firm jelly that holds its shape when turned out.
- Tomatoes
- Provide the main body, acidity and flavour of the jelly.
- Soup stock
- Adds savoury depth so the tomato base tastes less flat.
The step that matters
Dissolving the gelatine fully. Softened gelatine must be stirred into the warm tomato mixture until no granules remain. Undissolved gelatine leaves grainy patches and weak spots, so the jelly may not set evenly.
Flavor stand-ins for the clove
How well each one fits the dish's main ingredients (sugar, tomato, onion, garlic):
- Cuminbetter flavor fit
- Oreganobetter flavor fit
- Corianderbetter flavor fit
- Clovethe original
Fit is the average pairing score against sugar, tomato, onion, garlic. 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.
