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

What each ingredient does

Peanuts
Provide the main body, flavor, and thickness of the soup once mashed.
Butter
Adds richness and fat, carrying flavor through the soup.
Flour
Thickens the soup when cooked with the melted butter.
Milk or cream
Adds smoothness, richness, and a creamy texture.

The step that matters

Mix the butter and flour before adding. Cooking the flour in melted butter helps it dissolve smoothly and thicken the soup without lumps, so stir well when adding it to the liquid.
