Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red kidney beans
- Provide the main body and starchy, creamy texture of the dish.
- White onion
- Adds sweetness and savory depth as it softens during simmering.
- Garlic
- Contributes aroma and pungent savory flavor that mellows with cooking.
- Red wine
- Adds acidity and depth, balancing the richness of the beans.
- Brown rice
- Serves as the base that soaks up the bean liquid and absorbs flavor.
The step that matters
Soaking the beans in salt water. Dried kidney beans must be soaked and fully cooked; undercooked kidney beans can cause digestive upset. Soaking hydrates the beans so they cook evenly and become tender.
