Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red fish
- Forms the main body of the chowder as the protein.
- Flour
- Thickens the broth and browns to add color and body.
- Irish potatoes
- Add starch that softens and thickens the chowder as they cook.
- Tomatoes
- Add acidity and body to the broth.
- Lemon
- Adds acidity and bright citrus aroma to the chowder.
The step that matters
Cook the flour in the butter before adding liquid. Flour cooked briefly in melted butter forms a roux that thickens smoothly and browns for flavor. Adding liquid too early can leave lumps and a raw, pasty taste.
