Chocolate Biscuits

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Dissolve the chocolate in the water over low heat.

  2. Cream the butter and sugar together with the dissolved chocolate.

  3. Beat in the egg and add the vanilla extract.

  4. Sift in the flour and stir until combined.

  5. Turn the dough onto a floured surface and roll it into a thin sheet.

Shape and bake

  1. Cut into rounds or fancy shapes.

  2. Place on a greased baking sheet and bake for about 12 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Provides the structure that holds the cookies together as they bake.
Butter
Adds fat for tenderness and a rich texture in the finished cookie.
Castor sugar
Adds sweetness and, when creamed with butter, helps give a tender crumb.
Egg
Binds the dough and adds structure and richness.
Grated chocolate
Supplies the chocolate flavour and some fat to the dough.

The step that matters

Dissolving the chocolate in the water. Chocolate can seize or turn grainy if overheated, so melting it gently over low heat keeps it smooth and evenly mixed into the dough.
