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 ↓
Scotch Potato Scones
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 dough
Sift together the flour, salt, and baking powder.
Rub in the butter lightly after adding the mashed potatoes.
Make a soft dough by adding the beaten egg and a little milk if necessary.
Shape the scones
Divide the dough into three parts and roll each into rounds ½ inch thick.
Cut each round into four parts by making two cuts across.
Bake and serve
Bake in a 400°F (200°C) oven or on a griddle until done.
Split and butter the scones, then serve hot.

Flour and butter 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
- All-purpose flour
- Provides the starch and gluten structure that holds the scones together.
- Butter
- Rubbed into the flour to add tenderness and richness to the crumb.
- Mashed potatoes
- Add moisture and softness to the dough, keeping the scones tender.
- Baking powder
- Releases gas during baking, so the scones rise and become light.
- Egg
- Binds the dough and adds richness and structure to the scones.
The step that matters
Make a soft dough with only a little milk. Too much liquid makes the dough sticky and hard to shape, while too little leaves it dry and crumbly. Adding milk gradually lets you judge the texture. Light handling also keeps the scones tender rather than tough.
