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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
Sift together the flour, salt, and baking powder.
Add the mashed potatoes and rub in the butter lightly.
Make a soft dough by adding the beaten egg and a little milk if necessary.
Shape and bake
Divide the dough into three parts and roll each into rounds about ½ inch thick.
Cut each round across twice to make four parts, but do not cut all the way through.
Bake in the oven or on a griddle until done.
Serve
Split the scones, butter them, and serve hot.

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 main structure that holds the scones together as they bake.
- Butter
- Rubbed into the flour to add tenderness and richness to the crumb.
- Mashed potatoes
- Adds moisture and softness, keeping the scones tender after baking.
- Baking powder
- Releases gas when heated, helping the scones rise and lighten.
- Egg
- Binds the dough and adds richness and structure.
The step that matters
Make a soft dough by adding the beaten egg and a little milk if necessary.. Adding too much milk makes the dough sticky and tough, while too little leaves it dry and crumbly. Adding liquid gradually lets you reach a soft, workable dough that bakes up light.
