Ingredients
Directions

Toast the bread slices until dark brown, but do not burn them.
Place the toast in a deep bowl.
Steep and strain

Optionally, soak a piece of lemon peel with the bread for flavor.

What each ingredient does
- Dark brown bread
- Toasting browns the bread and builds its roasted flavor, which passes into the water as it soaks.
- Water
- Acts as the solvent that draws toasted flavor and color out of the bread during steeping.
The step that matters
Toast until dark brown, not burnt. Browning through heat creates the roasted flavor of the water. Burnt bread adds bitter, acrid compounds that dissolve into the water and spoil the final taste.
