Scotch Shortbread

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Prepare

  1. Place the flour on a clean surface.

  2. Add the butter and sugar to the flour.

  3. Knead the mixture with your hands until a smooth dough forms.

  4. Roll the dough into a round cake to your desired thickness.

Bake and shape

  1. Bake in a 350°F (175°C) oven for about 30 minutes, or until nicely browned.

  2. Cut into shapes while hot.

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

All-purpose flour
Forms the structure of the dough that holds the shortbread together.
Unsalted butter
Provides fat that makes the shortbread rich and tender.
Granulated sugar
Adds sweetness and helps the surface brown during baking.

The step that matters

Bake until nicely browned. Shortbread is baked until golden, not just set. Browning comes from sugar caramelizing and proteins reacting with heat, which adds flavor. Underbaking leaves it pale and soft, while overbaking makes it hard and dry.
