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 ↓
Highland Cookies
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, mix together the sugar, butter, and eggs until smooth.
Sift the flour and baking powder together, then add to the mixture.
Stir in the milk to form a soft dough that is easy to handle.
Shape and bake
Roll the dough thin on a floured surface and cut with a biscuit cutter.
Bake on a well-greased baking sheet for 5 to 6 minutes 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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that tenderizes the cookies and carries flavor.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Flour
- Forms the main structure of the dough once its starches set during baking.
- Baking powder
- Releases gas that lifts the cookies and gives them a lighter texture.
- Milk
- Adds moisture so the flour hydrates into a soft, workable dough.
- Sugar
- Sweetens the cookies and helps them brown at the edges in the oven.
The step that matters
Rolling the dough thin. Thickness controls how the cookies bake. Rolled too thick, they stay doughy in the middle and may not cook through in the short bake time. Rolling evenly also keeps them baking at the same rate.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
