Charcoal Biscuits

Oven, in the book's wordsA brisk oven

Ingredients

Directions

The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Sift the flour and add the charcoal, then sift again.

  2. Gradually mix in water until a stiff paste forms.

  3. If desired, add about 1 ounce of sugar.

Shape and bake

  1. Roll out the dough to ½ inch thick and cut into oblongs or squares.

  2. Bake in a brisk oven at 400°F (200°C).

Store

  1. Store in tins when completely cool.

What each ingredient does

All-purpose flour
Forms the main structure of the biscuits as it binds with water into a dough.
Fine willow charcoal
Gives the biscuits their dark color and characteristic charcoal flavor.
Sugar
Adds sweetness and helps the biscuits brown in the oven.

The step that matters

Gradually mix in water until a stiff paste forms. Adding water slowly lets the flour hydrate evenly, so the dough stays stiff enough to cut cleanly and does not turn sticky or tough.
