Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Soften during boiling and thicken the chowder as their starch releases into the broth.
- Clams
- Provide the main seafood flavor and tender bite in the chowder.
- Milk or cream
- Adds richness and a smooth, creamy body when stirred in at the end.
- Butter
- Adds fat for a rounded, savory richness and mouthfeel.
- Tomato soup or fresh tomatoes
- Adds acidity and color, giving the chowder a tangy, reddish character.
The step that matters
Stir in the milk or cream just before serving. Dairy added early can curdle or separate when held at a long boil. Adding it at the end, off a vigorous boil, keeps the chowder smooth and creamy.
