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

What each ingredient does

Milk
Forms the liquid base of the gruel and gives it a rich, creamy body.
Flour
Starch thickens the hot milk as its granules swell, giving the gruel body.

The step that matters

Adding the flour and water mixture to the milk. Flour mixed with cold water first disperses evenly, so its starch granules do not clump. Adding it to boiling milk while stirring lets the starch thicken smoothly instead of forming lumps.
