Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Italian sausage
- Renders fat and browns to build the savory base of the sauce.
- Red or dry white wine
- Lifts browned bits from the pan and adds acidity and depth to the sauce.
- Diced tomatoes
- Provide the main liquid, body and acidity of the sauce.
- Tomato paste
- Thickens the sauce and concentrates its savory, tomato flavor.
- Onion
- Softens and turns sweet as it cooks, adding aroma to the base.
The step that matters
Cook the sausage until cooked through and well browned. Browning the sausage creates flavorful caramelized compounds in the fat and pan, while cooking it fully ensures it is safe to eat. Breaking it up gives the sauce an even texture.
