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 ↓
Eveklasting Cookies
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
Preheat the oven to 400°F (200°C).
Make the dough
Cream together the butter and sugar.
Add the eggs, milk, and enough flour to form a soft dough.
Shape and bake
Roll the dough thin and sprinkle a little sugar over the top.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the cookies and, creamed with butter, helps give a tender crumb.
- Butter
- Adds fat for richness and tenderness, and carries flavor through the dough.
- Eggs
- Bind the dough and add structure as the cookies set in the oven.
- Baking powder
- Releases gas in the dough so the cookies rise and lighten.
- Flour
- Forms the main structure that holds the soft dough together when baked.
- Sweet milk
- Adds moisture to the dough and helps it come together.
The step that matters
Roll the dough thin. Thickness controls how the cookies bake. Thin dough cooks through and turns golden at an even rate, giving a crisp, evenly baked cookie instead of a thick, doughy centre.
“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.
