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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour and salt.
Cut in the lard or butter until crumbly.
Add the egg white and enough sweet milk to form a dough.
Shape and bake
Roll out the dough with a rolling pin for 20 minutes.
Shape the dough into balls the size of a pigeon's egg and roll them out thin.
Sprinkle flour on baking tins and place the wafers on them.
Bake until lightly golden, watching carefully.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Provides the structure that holds the thin wafer together as it bakes.
- Lard or butter
- Cut into the flour to make it crumbly, giving the wafers a tender, short texture.
- Egg white
- Adds protein that helps bind the dough and sets as it bakes.
- Sweet milk
- Adds moisture so the flour and fat come together into a workable dough.
The step that matters
Bake until lightly golden, watching carefully. Thin dough browns quickly because there is little mass to absorb heat. Removing the wafers once they are lightly golden prevents them from over-browning, turning bitter and brittle.
“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.
