What each ingredient does
- Stale bread
- Toasting browns the bread, and the browned crust gives the water its colour and toasty aroma.
- Boiling water
- Hot water draws flavour and colour out of the toasted bread into the liquid.
The step that matters
Toast the bread slowly until dark brown. Slow toasting browns the bread evenly through Maillard browning and caramelisation, building the toasty flavour. Rushing it can leave the bread pale inside or scorched and bitter on the outside, which affects the final taste.
