Plain 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.

Make the dough

  1. Rub the butter into the flour using your hands.

  2. Add the sugar and mix until smooth.

  3. Form the mixture into a ball and press it into a round or square cake pan.

Bake

  1. Prick the surface all over with a fork and pinch the edges.

  2. Bake in a moderate oven at 350°F (175°C) for 30 minutes.

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

What each ingredient does

Butter
Provides fat that coats flour particles, giving shortbread its tender, crumbly texture.
Flour
Forms the structure of the shortbread once mixed with butter and baked.
Sugar
Adds sweetness and helps the shortbread brown lightly during baking.

The step that matters

Rubbing the butter into the flour. The butter must be worked evenly into the flour so no large greasy pockets form. Overworking the dough, however, develops gluten and makes shortbread tough rather than crumbly.
