Spaghetti with Tomato Sauce

Ingredients

Directions

Cook the spaghetti

  1. Place a handful of spaghetti in a kettle of boiling salted water.

  2. As it softens, bend and coil it round in the kettle.

  3. Cover and cook for 15 to 20 minutes, or until tender.

  4. Drain in a colander.

Make the sauce and serve

  1. Return to the kettle with enough tomato sauce to make it moist.

  2. Add ⅓ cup of grated cheese, 1 tablespoon of butter, and a dash of paprika.

  3. Cook slowly until the sauce is mostly absorbed.

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 gives it its chewy, tender texture.
Tomato sauce
Adds moisture and acidity that coat the pasta as the sauce reduces.
Grated cheese
Adds salty, savory flavour and helps the sauce cling to the pasta.
Butter
Adds fat and richness, giving the sauce a smoother mouthfeel.

The step that matters

Cook slowly until the sauce is mostly absorbed. Gentle heat lets the sauce thicken and cling to the spaghetti without scorching the butter and cheese, which can turn grainy or burn on the bottom of the pan.

Swap the tomato

How well each one fits the dish's main ingredients (sauce, cheese, butter):

  1. Mustardfits better
  2. Tomatothe original
  3. Onionfits about as well
  4. Potatofits about as well

Fit is the average pairing score against sauce, cheese, butter. Candidates are from the same food group and used in at least 100 recipes.
