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

What each ingredient does

Oysters
Provide the main flavor and tender texture when cooked until they curl.
Butter
Adds richness and fat, carrying flavor through the soup.
Milk
Forms the creamy liquid base of the soup.
Onion
Softens and adds sweetness and aroma to the base.
Celery
Adds aromatic depth and a subtle savory note as it softens.

The step that matters

Stir in the chopped oysters and cook until they curl. Oysters turn firm and rubbery when overcooked, so they should be added to the hot milk and cooked only until their edges curl.

Swap the onion
