Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the base of the dish, carrying the sauce on its surface.
- Tomato paste
- Concentrates tomato flavor and thickens the sauce as it cooks down.
- Evaporated milk
- Adds creaminess and body to the sauce as its liquid reduces.
- Onion
- Softens while simmering, adding sweetness and savory depth to the sauce.
- Plum tomatoes
- Break down while simmering to add moisture and fresh tomato flavor.
The step that matters
Let the milk simmer until half the liquid evaporates. Reducing the liquid slowly at low heat concentrates flavor and thickens the sauce. Too high a heat can scorch the milk solids on the pan bottom, and stopping too early leaves the sauce thin and watery.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (salami, parmesan cheese, olive, pepper, plum, tomato, onion):
- Basilfits better
- Garlicfits better
- Oreganofits better
- Capersthe original
Fit is the average pairing score against salami, parmesan cheese, olive, pepper, plum, tomato, onion. Candidates are from the same food group and used in at least 100 recipes.
