Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Italian sausage: Browned first to add fat and savory flavor to the broth.
Uncooked rice: Absorbs liquid and softens as it simmers, thickening the soup and giving body.
Great northern beans: Add creamy texture and body that holds up through simmering.
Diced tomatoes: Provide acidity and liquid that balances the rich sausage.
