Shortbread Biscuits

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. Place flour and sugar on a clean surface.

  2. Keep butter in one lump and work it into the flour and sugar until well combined.

  3. Knead the mixture until thoroughly mixed.

Shape and bake

  1. Roll out the dough and cut it into finger shapes.

  2. Bake in a slow oven at 300°F (150°C) until lightly golden.

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

What each ingredient does

All-purpose flour
Provides the structure that holds the dough together as it bakes.
Unsalted butter
Adds fat that makes the biscuits rich and short, tender rather than chewy.
Sifted sugar
Adds sweetness and helps the biscuits brown lightly and stay tender.

The step that matters

Knead only until the dough comes together. Overworking dough develops gluten, which makes shortbread tough instead of crumbly. Mix just until the butter, flour and sugar are evenly combined.
