What each ingredient does
- Buttermilk
- Its acidity helps milk proteins clump into curds when heated.
- Treacle
- Adds sweetness and a dark, molasses-like flavour to the whey.
The step that matters
Heat until the mixture curdles. Heating gently lets the milk proteins separate into soft curds. Overheating can toughen the curds and cloud the whey, so watch for separation rather than boiling it hard.
