Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Scotch Shortbread
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
Cream the butter and sugar together.
Gradually add the flour and knead until perfectly smooth.
Shape and bake
Divide the dough into several round or square pieces and flatten them out thin.
Pinch the edges and prick the surface with a fork.
Bake in a moderate oven at 350°F (175°C) until golden brown.
Sprinkle with powdered sugar before serving.

Butter and flour 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
- Butter
- Provides fat that makes the shortbread rich and tender with a crumbly texture.
- Sugar
- Adds sweetness and helps the dough brown lightly during baking.
- Flour
- Provides the structure that holds the shortbread together as it bakes.
The step that matters
Knead until perfectly smooth. Working the flour in until the dough is smooth makes it hold together when rolled and shaped. Overworking after the flour is fully incorporated can make the shortbread tough, so stop once the dough is uniform.
