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

What each ingredient does

Onion
Softens over gentle heat to build a sweet, mellow base for the broth.
Potatoes
Soften during cooking and thicken the chowder slightly as their starch releases.
Butter or drippings
Carries the onion's flavour and adds richness to the chowder.

The step that matters

Cook the onion without browning. Low, gentle heat softens the onion and draws out its sweetness. Browning would make the flavour sharper and bitter-edged, changing the clean, mild character of the chowder.

Swap the onion

How well each one fits the dish's main ingredients (pepper, butter, potato):
