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 rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub the flour and butter together.
Mix in the sugar, eggs, and cinnamon.
Add the milk and work to a smooth dough.
Let the dough rest for half an hour.
Shape and bake
Roll into a sheet ¼ inch thick.
Cut into small round cakes or desired shapes.
Bake in a 400°F (200°C) oven until fawn colored.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
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 worked with butter and liquid.
- Butter
- Adds fat that makes the wafers tender and crisp rather than tough.
- Sugar
- Adds sweetness and helps the wafers brown during baking.
- Eggs
- Bind the dough and add richness and structure.
- Milk
- Adds moisture so the flour and fat come together into a smooth dough.
The step that matters
Work the dough to a smooth consistency. Adding the milk and working the dough until smooth evenly distributes the fat and liquid, which keeps the wafers consistent in texture. Under-worked dough can be crumbly, while overworking can make the wafers tough.
“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.
