Why it works: Tomato and oregano match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 2,767 recipes mention both. Both carry 2-hexenal, which smells green, leafy. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: bread
Directions
Prepare
Prepare vegetables and bread; set aside.
Make the cheese sauce
In a 10‑inch frying pan over medium heat, melt butter; add onion and cook, stirring occasionally, until lightly browned (about 10 minutes).
Stir in tomatoes (break up with a spoon) and their liquid, chiles, and oregano; reduce heat and simmer, uncovered, for 5 minutes.
Add cheese, a handful at a time, stirring until cheese is melted and mixture is well blended.
Serve
Transfer to a fondue pot or chafing dish and keep warm over the heat source.
Use vegetables and bread cubes or sticks as dippers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheddar cheese
- Melts into the sauce to provide the main body, rich flavour and creamy texture.
- Butter
- Adds fat and richness, and helps soften the onion before the sauce is built.
- Onion
- Adds savoury sweetness and aroma when cooked until lightly browned.
- Stewed tomatoes
- Contribute acidity and moisture that loosen the sauce as it simmers.
The step that matters
Add the cheese a handful at a time. Adding cheese gradually lets each portion melt evenly. Dumping it in at once can cause the cheese to clump or turn grainy and oily, since high heat makes the proteins seize and separate from the fat.

Fit is the average pairing score against butter, onion, tomato, cheddar cheese. 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).
