Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Provide the main body and starchy, creamy texture of the dish.
- Tomatoes
- Add moisture and acidity that brightens the beans and forms a sauce when fried.
- Butter or oil
- Carries the heat for frying and adds richness to the mixture.
The step that matters
Boil the beans until fully tender. Dried haricot beans need long, thorough cooking to soften their starch and cell walls. Undercooked beans stay firm and chalky, and they will not blend well with the tomatoes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
