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 ↓
Scotch Shortbread
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Beat the butter until creamy.
Gradually add the flour and mix well.
Incorporate the sugar and caraway seeds.
Work in the chopped almonds until the mixture is smooth.
Shape and bake
Divide the dough into six pieces.
Roll each piece into a square about 1 inch thick and pinch the edges.
Prick the surface with a fork and decorate with strips of candied orange peel.
Bake in a good oven at 400°F (200°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
- Butter
- Provides fat and richness, giving the shortbread its tender, crumbly texture.
- Flour
- Forms the structure of the dough once mixed with the butter.
- Pounded loaf sugar
- Adds sweetness and helps the shortbread brown lightly in the oven.
- Sweet almonds
- Add nutty flavour and a little richness to the dough.
The step that matters
Working in the almonds until smooth. Overworking the dough once flour is in develops gluten and makes shortbread tough rather than short and crumbly. Mix only until the dough just comes together and is smooth.
