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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the potato starter
Boil the potatoes until tender.
Mash the boiled potatoes.
Pour boiling water onto the mashed potatoes until it reaches a gruel-like consistency.
Add the sugar and yeast when the mixture is cool enough.
Set the mixture aside to rise until light.
Make the dough
Heat the milk until warm.
Melt the butter in the warm milk.
Add salt and enough flour to create a thick batter.
Set the batter aside to rise until light.
Work the dough for twenty minutes.
Let the dough rise again.
Shape and bake
Roll out the dough thinly.
Spread melted butter over the rolled dough.
Cut out biscuits using a tumbler.
Layer half of the biscuits over the other half.
Prick the biscuits several times.
Set the biscuits aside to rise again.
Bake for twenty minutes at 350°F (175°C).

Butter and flour 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
- Potatoes
- Add starch and moisture that give the dough a soft, tender crumb.
- Yeast
- Ferments the sugars to produce gas, making the dough rise and turn light.
- Flour
- Forms the gluten network that gives the dough its structure.
- Milk
- Adds moisture and richness, softening the crumb and aiding browning.
- Butter
- Adds fat that tenderises the crumb and gives a rich flavour.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
The step that matters
Work the dough for twenty minutes. Kneading develops the gluten network that traps the gas from the yeast. Under-kneaded dough rises weakly and bakes up dense.
Swap the potato
How well each one fits the dish's main ingredients (sugar, milk, butter, flour):
- Arrowrootfits about as well
- Sweet potatofits about as well
- Potatothe original
- Leekfits about as well
Fit is the average pairing score against sugar, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
