Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat and flavour as it browns, seasoning the base of the soup.
- Potatoes
- Soften as the soup simmers and add body and starch to the broth.
- Clams
- Provide the main seafood flavour of the soup.
- Flour
- Mixed with water and stirred in, it thickens the milk and broth.
- Milk
- Adds creaminess and richness to the broth.
The step that matters
Adding the flour and milk. Flour mixed with water first stops lumps from forming. Stirring it into the simmering soup then thickens it evenly. Milk added to a hard boil can curdle or scorch, so keep the heat gentle once it is in.
