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

What each ingredient does

Onions
Build the savory base and add sweetness as they soften in the broth.
Turnip
Adds body and a mildly sharp, earthy flavor as it cooks until tender.
Cabbage
Contributes texture and vegetable flavor that softens during simmering.
Green corn
Adds natural sweetness and a fresh, tender bite to the soup.
Cream
Adds richness and a smooth, mellow body to the finished soup.

The step that matters

Adding the cream just before serving. Cream held at a long boil can separate and turn grainy, and it thins out in flavor. Adding it at the end keeps the soup smooth and rich.

Swap the cabbage
