Lemon Short Cake

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.

Prepare the dough

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the butter and sugar until creamy.

  3. Add the grated lemon rind and mix well.

  4. Gradually work in the flour and knead the dough until smooth.

  5. Roll out the dough to about ½ inch thick and prick all over.

Shape and bake

  1. Grease a shallow jam‑sandwich tin and sprinkle with caster sugar.

  2. Press the dough into the tin, smoothing the top with a knife, and prick it again.

  3. Bake for about 20 minutes or until golden brown.

  4. Let cool before cutting into pieces.

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

What each ingredient does

Flour
Provides the structure that holds the shortbread together as it bakes.
Butter
Adds fat for a rich, tender crumb and a melting texture.
Sugar
Sweetens the dough and helps it brown during baking.
Lemon rind
Adds aromatic lemon oils that flavour the dough without extra liquid.

The step that matters

Baking until golden brown. Stopping too early leaves the shortbread pale and doughy, while overbaking makes it dry and hard, because butter and sugar set and brown only within a narrow window.

Swap the lemon

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