Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Break down when boiled and mashed to give the soup body and a thick, smooth texture.
Clams
Provide the main savory flavor and their juice adds a briny seafood taste to the broth.
Butter
Adds richness and a rounded flavor to the finished soup.
Flour
Thickens the soup by swelling in the hot liquid to add body.
Cream or milk
Adds richness and a smooth, mellow texture when stirred in warm at the end.

The step that matters

Add the warm cream or milk just before serving. Adding dairy to a boiling soup can cause it to curdle or separate, so it is stirred in warm, off the heat, just before serving.
