Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish (in the method)
- Provides the main body of the chowder, with flesh that flakes into the broth.
- Potatoes
- Soften during cooking and thicken the broth while adding body.
- Salt pork
- Its rendered fat carries flavor into the onion and the broth.
- Milk
- Adds creaminess and a mild sweetness to the finished chowder.
- Boston crackers
- Soak up liquid and help thicken the chowder slightly.
- Butter
- Adds richness and a rounded, savory flavor at the end.
The step that matters
Adding the scalded milk. Milk can curdle or scorch if it boils hard or is added to a very hot, acidic liquid. Scalding it first and adding it near the end, with the heat kept low, keeps the chowder smooth.
