Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the main body and starchy structure that thickens the soup when cooked and puréed.
- Salt pork
- Adds savoury, smoky flavour and fat as it slowly cooks with the beans.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Milk
- Adds moisture and creaminess, loosening the purée into a smooth soup.
The step that matters
Boiling the beans until fully tender. Beans must be completely soft before sieving, because undercooked starch granules stay firm and leave a grainy, uneven purée.
Swap the beans
How well each one fits the dish's main ingredients (pork, butter, milk):
- Peanutfits better
- Cocoafits better
- Soybeanfits better
- Beansthe original
Fit is the average pairing score against pork, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
