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 browned bits that add savory depth to the chowder base.
- Fish (in the method)
- Provides the main protein, which becomes tender as it cooks in the broth.
- Potatoes
- Add body and starch that thicken the chowder and make it more substantial.
- Rich milk
- Adds creaminess and richness to the broth.
- Butter and flour
- Form a roux that thickens the milky liquid into a smooth sauce.
The step that matters
Adding the butter and flour sauce. Flour must be cooked into the melted butter and whisked with hot liquid added gradually. Adding it all at once or cold causes lumps, so the sauce will not blend smoothly into the chowder.
