Why it works: Tomato and pepper 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 ↓
Spanish 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.
Cook the spaghetti
Break the spaghetti into small pieces and drop it into 3 quarts of salted boiling water.
Boil steadily for 30 minutes.
Drain the spaghetti in a colander and place it in a baking dish.
Add the can of tomatoes to the spaghetti.
Prepare the pork and onions
Run the pork steak through a meat chopper, season with salt and pepper, and fry until browned.
Finely chop the onions, season, and fry until browned.
Bake and serve
Add the browned onions and meat to the spaghetti.
Season with a little more salt, pepper, and ½ teaspoon paprika.
Bake at 350°F (175°C) for 30 minutes, adding a small amount of hot water if it appears dry.

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 absorbs the tomato and meat juices as it bakes.
- Pork steak
- Supplies the savoury meat flavour; browning it first adds depth to the dish.
- Onions
- Add sweetness and aroma when fried until browned.
- Tomatoes
- Provide moisture and acidity that season and loosen the spaghetti as it bakes.
The step that matters
Adding hot water during baking. Spaghetti keeps absorbing liquid in the oven, so if the dish looks dry, a small splash of hot water keeps it moist and prevents scorching at the surface.
Swap the onion
How well each one fits the dish's main ingredients (pork, tomato, pepper):

- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against pork, tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
