What each ingredient does

Flour
Thickens the milk into a smooth, thick gruel as it cooks.
Milk
Forms the liquid base and adds richness and body to the gruel.
Raisins
Add sweetness and a chewy texture to the finished gruel.

The step that matters

Mixing the flour into a smooth paste with cold milk. Flour added directly to hot liquid clumps, because the starch outside each grain gels before the inside can absorb liquid. Blending it first with cold milk separates the grains so they disperse evenly when stirred into the hot milk.
