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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter and sugar together until light and fluffy.
Add the egg and mix well.
Sift in the flour and baking powder, and mix until combined.
Shape and bake
Place the mixture in a pastry bag or squirt bottle.
Force the mixture onto a greased baking sheet.
Bake in a 400°F (200°C) oven for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming butter with sugar traps air, giving the biscuits a light, tender texture and rich flavour.
- Sugar
- Creams with butter to aerate the dough and adds sweetness and gentle browning.
- Flour
- Provides the structure that holds the biscuit shape as the dough sets in the oven.
- Egg
- Binds the creamed butter and sugar into a smooth dough and adds structure as it sets.
- Baking powder
- Releases gas in the oven, helping the biscuits rise and become lighter in texture.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy traps air in the fat. That air expands in the oven and helps set the texture. Under-creaming leaves dense biscuits, while the dough should be mixed only until combined once the flour is added to avoid toughening.
