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 ↓
Grafton Milk Biscuits
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sponge
Boil and grate the potatoes.
Add brown sugar and pour boiling water over the mixture to soften.
When tepid, add yeast and let it become light.
Warm the butter in the milk with a little salt.
Mix in enough flour to create a stiff sponge.
Shape and bake
Once risen, work the dough on a board and return it to rise again.
When risen, roll into cakes and let them stand for half an hour.
Bake in a hot oven at 400°F (200°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Provide starch and moisture that give the dough a soft, tender crumb.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Flour
- Forms the gluten network that traps gas and gives the dough its structure.
- Butter
- Adds fat that tenderises the crumb and enriches the flavour.
- Milk
- Adds moisture and milk proteins that brown the crust and soften the texture.
- Brown sugar
- Feeds the yeast and adds sweetness and a little browning.
The step that matters
Let the dough rise fully before shaping. Yeast needs time to produce enough gas to lighten the dough. Shaping or baking before it has risen properly leaves the biscuits dense, since the gluten network has not yet expanded to hold air.

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.
