Why it works: Tomato and swiss cheese match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 127 recipes mention both. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
The recipe
Ingredients
Contains: milk, wheat, soy, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Heat 1 ¾ cups tomato juice with garlic in the top of a double boiler until very hot.
Place the pot over boiling water and remove the garlic.
Add the cheese a small amount at a time, stirring constantly until melted.
Combine cornstarch, Worcestershire sauce, and seasonings with ¼ cup tomato juice; stir into the cheese mixture.
Continue stirring until smooth; if the fondue becomes too thick, add more tomato juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Swiss cheese or gruyere cheese
- Melts into the base to provide the main body, richness and flavor of the fondue.
- Cornstarch
- Thickens the melted cheese and helps keep it smooth and from separating.
- Tomato juice
- Provides the liquid that melts the cheese and sets the fondue's consistency and tangy flavor.
The step that matters
Adding the cheese gradually. Adding cheese in small amounts while stirring constantly lets it melt evenly. Dumping it in at once can clump or cause the cheese to turn stringy or grainy as it overheats.

Fit is the average pairing score against tomato, garlic, swiss cheese, sauce, basil, mustard, nutmeg. 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).
