What each ingredient does
- Thick slice of bread
- Browned bread provides toasty, roasted flavor and aroma that dissolves into the water.
- Boiling water
- Acts as the solvent that extracts flavor from the toasted bread and peel.
- Lemon peel or orange peel
- Adds bright citrus aroma and oils that lightly flavor the water.
The step that matters
Brown the bread well without burning it. Browning drives Maillard reactions that create the toasty flavor. Burnt bread turns bitter and carries that bitterness into the water.
