Why it works: Milk and butter 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 ↓
Biscuits, Bath Olivers
Ingredients
Directions
Make the dough
In a pan, cream together the yeast and sugar, then mix with the tepid milk.
Pour this mixture into a well in the flour, draw some flour into it, cover, and let it rise for 1.5 hours.
Work the risen mixture into the rest of the flour with the butter until smooth.
Let the dough rise again for 2 hours.
Shape and bake
Roll out the dough very thinly and stamp out biscuits with a cutter the size of a teacup.
Prick the biscuits well with a fork to allow steam to escape.
Place the biscuits on flat baking tins sprinkled with water.
Brush the biscuits with beaten egg yolk mixed with milk.
Let the tins sit in a warm place for 30 minutes, then bake in a slack oven.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine flour
- Provides the structure that holds the dough together and sets during baking.
- German yeast
- Produces gas during the two rises, making the dough light and airy.
- Butter
- Adds fat that tenderises the dough and gives the biscuits a rich flavour.
- Tepid milk
- Hydrates the flour and gives the dough moisture and softness.
- Egg yolk
- Brushed on top, it promotes browning and a glossy finish.
The step that matters
Prick the biscuits well with a fork. Pricking lets steam escape during baking so the biscuits stay flat and crisp rather than puffing or blistering unevenly.
