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 savory flavor through the broth and browns the onion.
- Potatoes
- Starch that softens during boiling and gives the soup body and a thicker texture.
- Clams
- Main seafood ingredient that supplies the characteristic briny, sea-like flavor.
- Flour
- Starch that thickens the milk and broth into a smoother, creamier consistency.
- Milk
- Adds richness and creaminess, softening the flavor and texture of the broth.
- Onion
- Releases sweetness and aroma as it cooks, building the soup's flavor base.
The step that matters
Adding the flour mixture. Flour must be mixed smoothly with water before stirring in, or it clumps and won't thicken evenly. Boiling afterward fully cooks the starch so it thickens and loses any raw floury taste.

Fit is the average pairing score against pork, potato, clam, flour, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
