Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salt pork
Renders fat for frying the onions and adds savory flavor to the base.
Onions
Soften and turn sweet as they cook, building the body of the chowder.
Flour
Cooked briefly with the fat and onions to thicken the chowder slightly.
Rice
Releases starch during the long simmer, helping to thicken the chowder.
Tomatoes
Provide the main flavor, acidity and liquid for the chowder.

The step that matters

Cooking the onions to light straw color. Onions cooked too briefly stay sharp and raw-tasting, while cooking them too far turns them bitter and brown. Gentle browning builds sweetness that balances the tomato acidity.

Swap the onion
