Thicken and serve
In a separate bowl, mix the sweet milk with 2 tablespoons of flour until smooth.
Add the milk mixture and pepper to the kettle, then bring to a boil and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sweet milk so the chowder becomes creamy rather than watery.
- Sweet milk
- Adds creaminess and richness to the broth.
- Fresh white fish or cod
- Provides the main flaky protein that cooks into the chowder.
- Sliced pork
- Renders fat and flavour into the kettle that seasons the stew.
- Irish potatoes
- Soften during stewing and add body to the chowder.
The step that matters
Mixing the flour into the milk. Flour clumps if added directly to hot liquid. Mixing it smooth in cold milk first lets the starch disperse evenly, so the chowder thickens without lumps.
Swap the onion

Fit is the average pairing score against pork, fish, potato, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
