Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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
Preheat the oven to 350°F (175°C).
Sift the baking powder and baking soda with the flour.
Make and shape the dough
In a bowl, mix the butter and sugar until crumbly, then add the flour mixture.
Stir in the milk until combined, then roll out the dough.
Cut the dough into squares or strips.
Sprinkle the tops with nuts or sugar before baking.
Bake
Bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake together as it sets.
- Butter
- Adds fat that makes the cake tender and rich in texture.
- Sugar
- Adds sweetness and helps the cake brown as it bakes.
- Milk
- Adds moisture that hydrates the flour and binds the dough.
- Baking powder
- Releases gas in the dough to help the cake rise.
- Baking soda
- Reacts with acidic ingredients to produce gas that helps the cake rise.
The step that matters
Stir in the milk until combined. Once flour is hydrated, overmixing develops gluten, which makes the cake tough rather than tender. Stop mixing as soon as the dough comes together.
