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 ↓

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.
Make the sponge
Combine milk, yeast, and flour to make a sponge and let it rise overnight.
Make the dough
In the morning, add more flour if needed to form a soft dough, then mix in eggs, cinnamon, butter, and sugar.
Knead the dough for 5 minutes and let it rise for 4 more hours.
Shape and bake
Break off pieces and shape them into small biscuits with floured hands.
Place the biscuits closely together in a baking pan and let them rise for another 30 minutes.
Bake in a moderate oven at 350°F (175°C), covering with paper if they brown too quickly.
Once baked, brush the tops lightly with butter and sugar to glaze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid that hydrates the flour and dissolves the sugar.
- Yeast
- Ferments the sponge and dough, producing gas that makes the biscuits rise.
- Flour
- Forms the gluten network that gives the dough its structure.
- Butter
- Adds fat that tenderises the crumb and gives richness.
- Eggs
- Add structure and richness, and help bind the soft dough.
- Sugar
- Feeds the yeast and adds sweetness and gentle browning to the crust.
The step that matters
Shaping and the second rise. Biscuits placed closely together should be given time to rise fully before baking, because yeast needs to build gas for a light texture. Watch the tops while baking, since sugar browns quickly and paper covering prevents burning.
“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.
