Shortbread, Scotch

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Beat the butter until creamy.

  2. Gradually add the flour and mix in the sugar and chopped almonds.

  3. Work the mixture until smooth and divide it into 5 pieces.

Shape and bake

  1. Roll each piece out on parchment paper to about 1 inch thick and pinch the edges.

  2. Prick the surface with a skewer and decorate with strips of candied orange peel.

  3. Bake in a moderate oven at 350°F (175°C) for 25 to 30 minutes.

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

What each ingredient does

Unsalted butter
Provides fat and richness, giving the shortbread its tender, crumbly texture.
All-purpose flour
Forms the structure of the dough once it is worked smooth.
Cornflour or ground rice
Lowers gluten formation, keeping the shortbread fine-textured and crumbly.
Caster sugar
Adds sweetness and helps the shortbread brown lightly in the oven.
Sweet almonds
Add nutty flavour and a little texture to the dough.

The step that matters

Working the dough until smooth. Overworking develops gluten in the flour, making the shortbread tough rather than tender. Mix only until the dough comes together smoothly, so the butter keeps it short and crumbly.

Swap the orange
