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 ↓

Ingredients
Directions
The book says “a sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a large bowl, mix the flour, eggs, sugar, ammonia, and butter until well combined.
Add lemon oil to flavor the mixture.
Roll out the dough using a rolling pin.
Top and bake
Brush the rolled dough with milk and sprinkle coarse sugar on 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
- Flour
- Forms the structure of the dough once combined with eggs and butter.
- Eggs
- Bind the dough and add richness and structure.
- Butter
- Adds fat for tenderness and a crisp, short texture.
- Sugar
- Adds sweetness and helps the surface brown as it bakes.
- Ammonia
- Acts as a leavening agent, lightening the dough as it bakes.
