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 Scones
Ingredients
Directions
Prepare the dough
Dissolve the baking soda and butter or lard in the warmed sour milk.
In a bowl, combine the flour and salt.
Pour the milk mixture into the flour and mix to form a stiff dough.
Roll out the dough into a round cake, ½ inch thick.
Bake and serve
Mark the dough into eight sections and bake on a griddle for 15 to 20 minutes.
Split and butter the scones while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the sour milk's acid to produce gas, so the scones rise.
- Sour milk
- Its acidity activates the baking soda and moistens the dough for a tender crumb.
- Butter or lard
- Adds fat that tenderises the crumb and carries flavour.
- All-purpose flour
- Forms the gluten network that gives the scones their structure.
The step that matters
Mix to a stiff dough. Overmixing develops too much gluten, making the scones tough, while underworking leaves dry pockets of flour. Mix just until the dough holds together.
