What each ingredient does
- Bread crusts
- Toasted until dark brown, they provide the coffee-like flavour and colour once steeped in water.
- Boiling water
- Extracts flavour and colour from the toasted crusts during steeping.
The step that matters
Drying the crusts until dark brown. Toasting browns the bread through the Maillard reaction and caramelisation, which creates the roasted, coffee-like flavour. Pale crusts will give a weak, bready drink.
