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 ↓
Chopped Puff Paste for Chicken Pie
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
Beat the egg until light, then mix in the lemon juice and ice water.
Sift the flour, sugar, and salt together in a bowl.
Chop the butter into the dry ingredients until crumbly.
Add the liquid mixture to the dry ingredients and combine.
Roll out the dough and fold it four times.
Bake
Bake in a hot oven at 400°F (200°C).

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
- Butter
- Forms flaky layers as it stays in pieces and creates steam when baked.
- Flour
- Provides the structure that holds the layers together as the pastry sets.
- Egg
- Adds richness and helps bind the dough and promote browning.
- Ice water
- Keeps the dough cold and limits gluten development for a tender result.
- Lemon juice
- Adds acidity that tenderizes the dough by slowing gluten formation.
The step that matters
Chop the butter into the dry ingredients until crumbly. The butter should stay in cold, separate pieces rather than fully blending in. When it melts in the oven, it releases steam that separates the dough into flaky layers.
