Why it works: Buttermilk and rosemary work together. They rank in the top 28% of all ingredient pairs, and cooks put them together in 29 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Treacle Whey
Ingredients
Directions
Add a large spoonful of treacle to a pint of boiling buttermilk.
If desired, add a sprig of rosemary.
Allow the mixture to curdle sufficiently, then strain it from the curd.
If the whey is too sweet, dilute it with water.

What each ingredient does
- Buttermilk
- Its acidity and milk proteins curdle when hot, separating curd from the liquid whey.
- Treacle
- Adds sweetness and a deep, molasses-like flavour to the whey.
The step that matters
Allow the mixture to curdle sufficiently. Heat and acid make the milk proteins clump into curds. If it is not left long enough, the curds stay loose and the whey comes out cloudy and weakly separated.
