Why it works: Bread and lemon are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 8,445 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Toast and Water
Ingredients
Directions
Prepare the toast
Cut a crust of stale bread about twice the thickness of regular toast.
Toast the bread until completely browned, but not burnt.
Infuse and serve
Pour boiling water into a jug to your desired amount.
Add the toasted bread to the jug and let it stand until completely cold.
For added flavor, infuse with lemon, orange peel, currant jelly, or apples.
If using a mug, cover the bread with boiling water, let it cool, then fill with cold spring water and strain.

What each ingredient does
- Stale bread
- Toasted bread releases browned, roasted flavor and aroma into the water as it steeps.
- Boiling water
- Hot water extracts flavor and color from the toasted bread, turning it into a drink.
The step that matters
Toast the bread until completely browned, but not burnt. Toasting browns the starches and creates the roasted flavor the drink depends on. Burnt bread adds bitter, acrid notes that carry into the water, while pale bread gives a flat, weak flavor.
