Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Shortbread, Scotch
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Beat the butter until creamy.
Gradually add the flour, then mix in the sugar and chopped almonds.
Work the mixture until smooth and divide it into three pieces.
Shape and bake
Roll each piece out on parchment paper to about 1 inch thick and pinch the edges.
Prick the surface with a skewer and decorate with strips of candied orange peel.
Bake in a preheated oven at 350°F (175°C) for 25 to 30 minutes.

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 shortbread together.
- Unsalted butter
- Supplies fat for a tender, crumbly texture and rich flavour.
- Cornflour or ground rice
- Lowers the gluten in the dough, giving a finer, more crumbly texture.
- Caster sugar
- Adds sweetness and helps the shortbread brown lightly in the oven.
The step that matters
Working the dough until smooth. Overworking or adding too much flour makes the dough tough, while insufficient mixing leaves it crumbly and hard to shape. Smooth, evenly combined dough bakes into a tender, cohesive shortbread.
