What each ingredient does
- Stale bread
- Toasted bread gives the water a mild, toasty flavor as it steeps.
- Orange or lemon peel
- Citrus peel adds a light aroma to the water.
The step that matters
Toasting the bread until golden, not burnt. Toasting browns the starches and develops flavor through the Maillard reaction. Burnt bread turns bitter and carries that bitterness into the water, so stop when the bread is golden.
