Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down slowly during simmering, releasing starch that thickens and gives the chowder body.
- Clams
- Provide the main seafood flavour, and their juice adds briny depth to the broth.
- Salt pork
- Its rendered fat carries savoury flavour through the chowder.
- Onions
- Soften and sweeten as they cook, building a mellow aromatic base.
- Butter
- Adds richness and a silky mouthfeel to the finished broth.
- Milk or cream
- Adds creaminess and a smooth, rounded texture to the soup.
The step that matters
Do not boil after adding the milk. Milk and cream can curdle, separate, or scorch when held at a hard boil. Keeping the heat gentle after adding dairy preserves a smooth, uniform texture.
