Scotch Short Cake

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.

Make the dough

  1. Cream the butter and sugar together until smooth.

  2. Add the egg yolk and mix well.

  3. Gradually sift in the all-purpose and rice flour, mixing until a dough forms.

Shape and bake

  1. Roll the dough to about ½ inch thick and cut into squares.

  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 main structure that holds the dough together after baking.
Rice flour
Adds a fine, crisp, tender texture because it has little gluten.
Unsalted butter
Supplies fat that makes the shortbread rich and tender, and carries flavor.
Sugar
Sweetens the shortbread and helps it brown lightly in the oven.
Egg yolk
Adds richness and helps bind the butter and flour into a cohesive dough.

The step that matters

Bake slowly until lightly golden. A slow oven dries and sets the shortbread evenly without over-browning it. A hotter oven can brown the edges before the centre is cooked through, and the sugar and butter darken quickly.
