Why it works: Flour and butter 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 ↓
English 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.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix and rub together the flour, sugar, and butter until the mixture is a nice mellow color and easy to work with.
Add the eggs and mix until combined.
Shape and bake
Weigh off the desired size and shape into square or round pieces.
Dock the tops and notch the sides.
Place on clean, dry baking sheets and bake until lightly golden.
Optionally, decorate the tops with designs of neatly‑cut lemon peel and caraway confections.

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 tender, crumbly texture and rich flavor.
- Sugar
- Adds sweetness and helps the surface brown lightly in the oven.
- Eggs
- Bind the dough and add moisture so the pieces hold together.
The step that matters
Rubbing in the butter and sugar. Working the butter into the flour and sugar until evenly mellowed matters because overworking develops gluten and makes the shortbread tough, while underworking leaves greasy pockets and an uneven crumb.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
