What each ingredient does

Milk
Its proteins clump into the curd that gives the posset its body.
Treacle
Adds sweetness and a deep, molasses-like flavour.

The step that matters

Boil until the curd separates. Heat causes the milk proteins to clump into curds and separate from the whey. Watching for this stage matters, because boiling well past it can make the curd tough and grainy.
