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.

Make the dough

  1. Beat the butter until creamy.

  2. Gradually add the flour and sugar, mixing well.

  3. Incorporate the chopped almonds until smooth.

Shape and bake

  1. Divide the dough into 6 pieces.

  2. Roll each piece into a square about 1 inch thick on parchment paper.

  3. Pinch the edges to shape and prick the surface with a skewer.

  4. Decorate with 1 or 2 strips of candied orange-peel.

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

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

Butter
Creamed butter gives the shortbread its rich, tender texture and fat-based flavour.
All-purpose flour
Provides the structure that holds the shortbread together as it bakes.
Cornflour or ground rice
Makes the shortbread more tender and crumbly by diluting the gluten in the flour.
Caster sugar
Adds sweetness and helps create the fine, crisp texture of the shortbread.
Sweet almonds
Add nutty flavour and a little richness to the dough.

The step that matters

Shape and bake. Pricking the surface lets steam escape so the shortbread bakes flat rather than puffing. Baking long enough until golden sets the crumbly texture, while underbaking leaves it soft and pale.

Swap the orange
