Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

What each ingredient does

Boiled flour
Thickens the liquid into a smooth gruel as its starch swells when heated.
Milk or water
Forms the liquid base that the flour thickens into a gruel.

The step that matters

Mixing the flour with water until smooth. Flour lumps if poured into hot liquid without first being blended into a smooth paste with cold water. Starch granules then hydrate separately, so the gruel stays lump-free once the boiling liquid is added.
