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.
Prepare the potato mixture
Boil and mash the potatoes.
Add brown sugar and pour boiling water over the mixture to soften.
Make the dough
When tepid, add yeast and let it rise until light.
Warm the butter in the milk, then add salt and baking soda.
Mix in enough flour to form a stiff sponge.
Once risen, work the dough on a floured surface.
Return the dough to the tray to rise again.
Shape and bake
When risen, roll into cakes and let them stand for 30 minutes.
Bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White potatoes
- Add starch and moisture, giving the dough a soft, tender crumb.
- Yeast
- Ferments the sugars and produces gas, so the dough rises until light.
- Butter
- Adds fat, which softens the crumb and adds richness to the biscuits.
- Milk
- Adds moisture and richness, and helps the dough brown in the oven.
- Baking soda
- Reacts with the dough's acidity to add lift and help browning.
- Flour
- Provides the structure that holds the stiff sponge and shaped cakes together.
The step that matters
Letting the dough rise until light. Yeast needs warmth and time to ferment; if the dough is too cool or rises too little, the biscuits stay dense. Over-rising can leave them collapsed, so the dough should be risen but not overly slack.
Swap the potato
How well each one fits the dish's main ingredients (sugar, butter, milk, flour):
- Arrowrootfits about as well
- Sweet potatofits about as well
- Potatothe original
- Leekfits about as well
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.
