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
Cut a crust of bread from a stale loaf, about twice the thickness of regular toast.
Toast the bread until completely browned, but not burnt.
Make the toast water
Place the toasted bread in a jug and pour boiling water over it to your desired amount.
Cover the jug and let it stand until completely cool.
For added flavor, infuse with lemon, orange peel, currant jelly, or apples.

What each ingredient does
- Stale bread
- Its dry crumb and toasted crust release browned flavour into the water.
The step that matters
Toast the bread until completely browned, but not burnt.. Toasting drives the Maillard browning and caramelisation that give the water its colour and flavour. Burnt bread turns bitter and carries acrid notes into the drink.
