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 body.
- Bacon
- Adds fat and savory flavor as it fries and browns.
- Tomatoes (in the method)
- Provide moisture and acidity that flavor the sauce.
- Cheese
- Melts and browns on top, adding richness and a golden crust.
The step that matters
Bake until brown. The topping of cheese and cracker crumbs browns through dry heat, which forms the golden crust. Baking too briefly leaves it pale and the dish underheated. Watch the color rather than relying only on time.
Swap the onion
How well each one fits the dish's main ingredients (cheese, rice):

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