Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ricotta cheese
- Adds creaminess and body, thickening the sauce into a smooth, rich coating.
- Heavy cream
- Adds fat and richness, giving the sauce a silky texture and mellowing the tomato.
- Plum tomatoes
- Provide the main tomato base, moisture and acidity for the sauce.
- Onions
- Build sweetness and savory depth as they soften in the oil and butter.
- Rigatoni pasta
- Provides the starchy base that holds the sauce in its ridges and tubes.
- Parmesan cheese
- Adds salty, savory flavor and a sharp finish over the top.
The step that matters
Simmering the sauce after adding ricotta and cream. Ricotta and cream can separate or turn grainy if boiled hard, so keep the sauce at a gentle simmer once they go in.
