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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Sift the baking powder through the flour.
Mix in the butter and milk until combined.
Roll out the dough and cut into desired shapes.
Bake
Wash the tops with beaten egg.
Bake in a hot oven at 400°F (200°C) 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 main structure of the biscuit crumb as it sets in the oven.
- Baking powder
- Releases gas in the dough, lifting the biscuits so they rise and turn light.
- Butter
- Melts in the oven, creating layers and a tender, flaky texture.
- Milk
- Hydrates the flour to form the dough and adds moisture and browning.
- Egg
- Brushed on top, it promotes an even golden colour when baked.
The step that matters
Roll out the dough and cut into desired shapes. Handling the dough too much or pressing the cutter down firmly can develop gluten and seal the edges, making the biscuits tough and stopping them rising evenly.
“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.
