What each ingredient does

Milk
Forms the creamy base that curdles and thickens into a soft, set texture when boiled with treacle.
Treacle
Adds sweetness and a deep, rich flavour, and its acidity helps curdle the milk.

The step that matters

Letting the milk curdle. Once treacle is added, the milk proteins clump as the mixture boils. Watch for curdling and stop at that point, since prolonged boiling can make the posset grainy and tough.
