Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Italian Spaghetti
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Melt butter in a skillet and fry the pork chops, sweet pepper, and onion until light brown.
Cook the tomatoes for 10 minutes, then let them cool.
Combine the cheese, cooked ingredients, and tomatoes in a bowl.
Bake and serve
Pour the mixture over the cooked spaghetti.
Bake at 350°F (175°C) for 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the bulk of the dish and holds the sauce together.
- Pork chops
- Provide savory meat flavor and substance once browned.
- Cheese
- Melts into the mixture to add richness and binding.
- Tomatoes
- Add moisture, acidity and body to the sauce.
- Onion
- Adds aroma and sweetness as it softens and browns.
The step that matters
Frying the pork chops, pepper and onion until light brown. Browning builds deep savory flavor through the Maillard reaction; pale frying leaves the sauce tasting flat.
Swap the onion
How well each one fits the dish's main ingredients (pepper, pork, tomato, cheese, butter):
- Capsicumfits better
- Potatofits better
- Onionthe original
- Mustardfits about as well
Fit is the average pairing score against pepper, pork, tomato, cheese, butter. Candidates are from the same food group and used in at least 100 recipes.
