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 ↓
Sweet or Biscuit Crust
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Place the flour on a clean surface and add the egg yolks, mixing until the egg is no longer visible.
Incorporate the sugar and mix well into the flour.
Add the butter and mix until combined.
Gradually add water or milk to form a stiff paste.
Knead the dough until smooth, then roll it to an eighth of an inch thick.
Glaze and bake
Use the dough for tarts, glazing them before or after baking.
To glaze, beat the egg white and spread it on top, then sprinkle with sugar.
Dampen the sugar slightly with water and sprinkle more sugar on top.
Bake in a slow oven at 300°F (150°C) and notch the edges finely.

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
- Forms the structure of the dough once bound with liquid.
- Egg yolks
- Add richness and help bind the dough.
- Butter
- Adds fat that makes the crust tender and rich.
- Sugar
- Adds sweetness and helps the glaze brown and crisp.
The step that matters
Gradually add water or milk to form a stiff paste. Adding liquid too quickly can make the dough sticky and hard to handle, while too little leaves it crumbly. Adding it slowly lets the flour absorb just enough moisture to form a smooth, workable dough.
