Good Scottish 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. In a bowl, mix the flour, sugar, and candied orange or citron.

  2. Add the melted butter and combine to form a paste.

  3. Press the paste together with your hands and mold it into large cakes about 1 inch thick on baking tins.

  4. Pinch the edges of the cakes.

Bake

  1. Bake in a preheated oven at 350°F (175°C) for 20 minutes or longer until crisp but not deeply colored.

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 paste and gives the shortbread its body.
Unsalted butter
Provides fat that makes the shortbread rich, tender and crumbly when melted into the dough.
Granulated sugar
Adds sweetness and helps the shortbread brown lightly and crisp during baking.
Candied orange or citron
Adds aromatic citrus flavor and a chewy bite throughout the shortbread.

The step that matters

Bake until crisp but not deeply colored. Shortbread sets as it bakes and firms as it cools. Removing it too late causes deep browning and a bitter taste from the sugar, while removing it too early leaves it soft and crumbly rather than crisp.

Swap the orange

How well each one fits the dish's main ingredients (flour, sugar, butter):

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Orangethe original

Fit is the average pairing score against flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
