Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that carries flavour into the soup base.
- Flour
- Thickens the milk mixture so the soup becomes slightly creamy.
- Milk
- Adds richness and a creamy body to the soup.
- Clams
- Provide the main seafood flavour of the soup.
The step that matters
Pour the milk mixture into the soup and let it boil for about 5 minutes. Flour mixed with milk must be stirred smooth before it is added, and the soup then needs to simmer or boil. Boiling activates the starch so the soup thickens, while adding flour in lumps leaves pasty clumps.
Swap the onion
How well each one fits the dish's main ingredients (pork, clam, flour, milk, butter, pepper, sauce):
- Potatofits better
- Capsicumfits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against pork, clam, flour, milk, butter, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
