Biscuits, Coffee

Oven, in the book's wordsA slow oven

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 dough

  1. Preheat the oven to 300°F (150°C).

  2. Rub the butter into the flour.

  3. Add the sugar and mix with coffee essence.

  4. Knead the mixture until smooth.

Shape and bake

  1. Roll out the dough and cut into strips 1 inch wide and 2 inches long.

  2. Place a small strip of citron on each strip.

  3. Bake on a greased baking sheet until lightly golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Flour
Forms the structure of the dough that holds the biscuit together.
Butter
Adds fat that makes the biscuits tender and rich in texture.
Sugar
Adds sweetness and helps the biscuits brown lightly in the oven.
Coffee essence
Gives the biscuits their coffee flavour.

The step that matters

Knead the mixture until smooth. Kneading develops gluten so the dough holds its shape when cut and baked. Kneading too little leaves the dough crumbly, while overworking can make the biscuits tough.
