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
Make the whey

What each ingredient does
- Buttermilk
- Its acids curdle when boiled, separating the curds from the liquid whey.
- Treacle
- Adds sweetness and a dark, rich flavour to the whey.
The step that matters
Allowing the mixture to curdle sufficiently. The curds only separate properly once the buttermilk is hot enough and has been left long enough for its proteins to coagulate. If the curdling is incomplete, the strained liquid will be cloudy and thin, with little of the separated whey character the drink depends on.
