Why it works: Butter and flour 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 ↓
Rich Puff Paste
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a bowl, mix half the flour with a quarter of the shortening and enough cold water to form a stiff dough.
Roll out the dough on a floured surface using a rolling pin.
Laminate
Cover the dough with bits of butter and lard alternately.
Sprinkle the dough thickly with flour using a dredge box.
Fold the dough over and roll it out again.
Repeat the process of adding butter and lard, sprinkling with flour, and rolling out until all ingredients are used.
Bake
Bake in a moderately heated oven at 350°F (175°C) for best results.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour 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
- Shortening (butter and lard)
- Creates layers of fat that separate the dough, producing a flaky, tender texture when baked.
- Flour
- Forms the gluten structure that holds the dough together and supports the layers.
- Cold water
- Hydrates the flour into a stiff dough while keeping the fat cold and separate.
The step that matters
Keeping the fat in pieces between rolled layers. If the fat softens or blends into the dough, it cannot form separate layers, so the pastry loses its flakiness. Keeping everything cold and rolling gently preserves the distinct fat layers that steam and lift during baking.
