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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Combine flour and egg in a bowl.
Gradually add water until the mixture is stiff and pliable.
Knead the dough with the heel of your hand until it can stretch into strings.
Work the butter until it becomes tough.
Roll the dough thickly.
Place all the butter in the center of the dough and fold it evenly around the butter.
Roll the dough again.
Fold it in regular folds.
Repeat this process three times.
Shape and bake
Roll the dough to the desired thickness, about ¼ inch for pates.
Cut out shapes with a cutter and place them on a baking sheet.
Brush the tops with a mixture of egg and a little water, being careful not to let the mixture touch the sides.
Use a smaller cutter to make a shallow cut in the center of each piece.
Bake in a preheated oven at 400°F (200°C) for a short time, watching closely to prevent over-browning.
Finish
Remove the tops and scoop out the soft pastry from inside.
Place on paper towels to absorb excess butter.

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 gluten network that gives the dough its structure and stretch.
- Unsalted butter
- Forms separate layers within the dough that puff apart as moisture turns to steam in the oven.
- Egg
- Binds the dough and, brushed on top, promotes even browning and a glossy finish.
The step that matters
Folding the butter into the dough. The butter must stay cold and in distinct layers. If it softens or blends into the dough, the layers won't form, so the pastry won't puff when baked.
“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.
