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
Prepare the dough
Keep all ingredients cold.
In a bowl, combine flour and salt.
Add shortening and chop into pea-sized pieces.
Moisten with ice water, mixing lightly with a fork.
Laminate
Turn out onto a floured surface and shape into an oblong.
Roll into an oblong sheet.
Fold into thirds, turn halfway, and roll again.
Fold again, turn halfway, and roll out for a third time.
Brush off excess flour, roll like a jelly roll.

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).
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
- Provides the structure that holds the dough together as it is rolled and folded.
- Shortening
- Pea-sized fat pieces stay solid in the dough and melt in the oven, creating flaky layers.
- Ice water
- Moistens the flour so the dough holds together without warming the fat.
The step that matters
Keep the fat pieces and dough cold. If the shortening softens or melts before baking, it blends into the flour instead of forming separate layers, so the pastry turns dense rather than flaky.
