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 the savory, briny character of the soup.
Rich milk
Adds body, creaminess and a soft, mellow texture to the broth.
Butter
Adds fat for richness and a smooth mouthfeel in the finished soup.
Cracker crumbs
Thicken the liquid slightly and add a toasty, starchy body.

The step that matters

Heating the milk separately in a double boiler. Milk can curdle or scorch when it is held at high heat. Gentle heating in a double boiler keeps it smooth, so adding it to the boiling kettle does not cause it to separate.
