Crust Coffee
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the crusts
Place crusts of bread in a 300°F (150°C) oven until very crisp and brown.
Break the crusts into small pieces.
Brew
Cover the pieces with boiling water.
Wait until the water has been absorbed.
Add more boiling water to cover the bread.
Set the mixture at the back of the range or over boiling water for 15 minutes.
Strain through cheesecloth.
Serve
Serve hot or cold.

What each ingredient does
- Crusts of bread
- Toasting dries and browns the crusts, giving the brew its roasted, coffee-like flavour.
- Boiling water
- Extracts flavour and colour from the toasted bread as it soaks and steeps.
The step that matters
Toasting the crusts until very crisp and brown. Toasting drives off moisture and triggers browning reactions that create the roasted flavour and colour. Under-toasted crusts will taste flat and bready, while over-toasted ones turn bitter and burnt.
