Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the main body of the dish, and their starch softens into a tender, creamy texture when cooked.
- Butter
- Adds richness and fat, coating the beans and giving them a smooth mouthfeel.
The step that matters
Cook until tender. Beans need to be fully cooked for their starch to soften. Stopping at the stated time before they are tender leaves them firm and chalky, so check for softness rather than relying only on the clock.
Swap the beans
How well each one fits the dish's main ingredients (pepper, butter):
