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

What each ingredient does

Fine flour
Its starch thickens the liquid as it heats, giving the caudle body.
Milk
Forms the liquid base and adds richness and a creamy texture.
Sugar
Sweetens the caudle and adds flavor to the milk.

The step that matters

Pouring the flour and water mixture into the boiling milk. If the flour mixture is not smooth or is poured in carelessly, lumps can form as the starch hits the hot liquid. Stirring continuously while it cooks keeps the starch dispersed so the caudle thickens evenly.
