Scotch Shortbread

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.

Prepare the dough

  1. Sift the flour and salt into a bowl.

  2. Add the sugar and rub in the butter until well combined.

  3. Turn the mixture onto a pastry board and knead until smooth.

Shape and bake

  1. Shape the dough into a round and pinch the edges.

  2. Place it on a baking sheet lined with buttered paper.

  3. Prick the top with a fork and tie a band of stiff buttered paper around the outside.

  4. Optionally, place a small piece of citron on top before baking.

  5. Bake in a slow oven at 300°F (150°C) for about 45 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.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: guaiacol (smoky, sweet).

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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 structure that holds the shortbread together as it bakes.
Unsalted butter
Adds richness and tenderness by coating flour particles and keeping the crumb short.
Sugar
Adds sweetness and helps the shortbread brown lightly in the oven.

The step that matters

Rub in the butter until well combined. Working the butter into the flour evenly coats the flour particles, which limits gluten formation and gives the shortbread its tender, crumbly texture. Uneven or overworked butter can make it tough or greasy.
