Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flavor and texture of the soup.
- Flour
- Thickens the soup as it is cooked with the butter and liquid.
- Butter
- Adds richness and carries flavor, and mixed with flour it helps thicken the soup.
- Milk
- Adds creaminess and body, mellowing the broth.
The step that matters
Stir the flour and butter mixture into the pot off the heat. Adding a flour-butter paste to hot liquid off the heat lets it disperse before thickening. Stirred in over direct heat, the flour can clump into lumps that are hard to smooth out.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
