Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
A Good Recipe for Household Pies and Tarts
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
In a bowl, combine the flour, salt, and baking powder.
Cut the butter and lard into small lumps and add to the flour mixture.
Mix until a stiff paste forms, using a knife.
Laminate and shape
Roll out the dough four or five times, folding it in thirds each time and turning it before rolling again.
When the butter is fully incorporated, roll the dough into the desired shape.
For fruit tarts, do not place sugar on top to keep the pastry light.
For meat pies, make a small hole at the top to allow steam to escape.
Bake
Preheat the oven to 400°F (200°C) and do not open the door for the first 10 minutes.

Shared aroma: isobutyraldehyde (malty, green).
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
- All-purpose flour
- Forms the structure of the dough, holding the layers together as it bakes.
- Unsalted butter
- Creates separate layers that puff up with steam as the pastry bakes.
- Lard
- Adds flakiness and tenderness by keeping layers distinct during baking.
- Baking powder
- Helps the pastry rise and lighten during baking.
The step that matters
Rolling and folding the dough. Folding and rolling spread the fat into many thin layers. If the butter is not fully incorporated or the dough warms and softens, the fat blends into the flour, and the pastry loses its layers and puff.
