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

What each ingredient does

Flour
Its starch thickens the milk as it cooks, giving the pap body.
Milk
Forms the liquid base that the starch thickens into a creamy porridge.
Loaf sugar
Adds sweetness to the finished pap.

The step that matters

Mixing the starch into cold milk before adding it to boiling milk. Starch granules clump if they hit hot liquid dry or unmixed. Blending the grated flour smoothly into cold milk first lets it disperse evenly, so it thickens the boiling milk without lumps.
