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

What each ingredient does

Pinto beans: Provide the main body and protein-rich bulk of the dish.
Cooked rice: Adds bulk and soaks up the sauce, making the dish filling.
Barbecue sauce: Supplies sweetness, acidity and flavour that coat the beans and rice.
Onion: Softens as it cooks, adding sweetness and aroma to the base.
Green bell pepper: Softens as it cooks, adding a fresh, slightly bitter vegetable note.
