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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Boil the potatoes.
Mash the boiled potatoes.
Add brown sugar to the mashed potatoes.
Pour boiling water over the mixture to soften.
When tepid, add yeast.
Let the dough rise until light.
Make the dough
Warm the butter in the milk.
Add salt and baking soda to the butter‑milk mixture.
Mix in enough flour to create a stiff sponge.
Work the dough on a floured surface.
Return the dough to the tray to rise again.
Shape and bake
Roll the risen dough into cakes.
Let the cakes stand for 30 minutes.
Bake in a preheated 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
- White potatoes
- Their starch and mash give the dough moisture and a soft, tender crumb.
- Yeast
- Ferments the sugars in the sponge, producing gas that makes the dough rise and become light.
- Flour
- Forms the gluten network that gives the stiff sponge and dough their structure.
- Butter
- Adds fat that tenderises the crumb and gives a rich flavour.
- Milk
- Adds moisture and milk solids that help browning and a soft texture.
- Baking soda
- Reacts with the acidity in the dough to add lift and help browning.
The step that matters
Letting the dough rise until light. Yeast needs time and warmth to produce enough gas for a light crumb. Rising too briefly leaves dense biscuits, and the second rise after shaping helps build the final texture.

Fit is the average pairing score against sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
