Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh white fish
- Forms the body of the chowder, flaking into tender pieces as it simmers.
- Potatoes
- Add starch and body, thickening the broth slightly as they cook.
- Milk
- Adds creaminess and richness to the broth.
- Butter
- Adds fat and richness, carrying flavor through the chowder.
- Flour
- Thickens the milk mixture so it blends smoothly into the chowder.
- Bacon
- Adds smoky, salty fat that flavors the broth.
The step that matters
Scalding and stirring in the milk mixture. Adding cold or boiling milk too fast can cause curdling or lumps. Scalding the milk and blending it smoothly with butter and flour first lets the starch disperse evenly, giving a smooth, stable chowder.
