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
Cream together the yeast and sugar.
Mix with the tepid milk and pour into a well in the flour.
Draw some flour into the mixture, cover, and let it rise for 1.5 hours.
Work in the butter to form a smooth dough and let it rise for 2 hours.
Shape and bake
Roll out the dough thinly and cut into biscuits with a plain cutter.
Prick the biscuits with a fork to allow steam to escape.
Place on baking tins sprinkled with water and brush with beaten egg yolk mixed with milk.
Let the biscuits rise in a warm place for 30 minutes.
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
- Forms the main structure of the dough once mixed with liquid and fat.
- German yeast
- Produces gas during the long rises, leavening the dough.
- Butter
- Adds fat that tenderises the dough and gives the biscuits a rich texture.
- Tepid milk
- Hydrates the flour and feeds the yeast, forming the dough.
- Egg yolk
- Brushed on top to promote browning and a glossy finish.
The step that matters
Bake in a slack oven. A slack, moderate oven heats the biscuits gently so they dry and colour evenly without scorching. A hot oven would brown the surface before the interior sets and dries.
“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.
