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 ↓
Short Puff-paste
Ingredients
Directions
Make the dough
In a bowl, mix the flour, egg, half the butter, and two-thirds of the water until smooth and firm.
Spread the mixture out with your hands, placing the remaining butter in the center.
Fold the sides over to completely enclose the butter.
Roll and fold
Let the paste rest for 5 minutes, then dust with flour and roll it out to about 30 inches long and 12 inches wide.
Fold the rolled paste into thirds, turn it so the sides face you, and roll it out again.
After 10 minutes, repeat the rolling process two more times. The paste is now ready to use.

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
- Flour
- Forms the gluten network that gives the paste its structure and holds the layers together.
- Butter
- Forms separate layers that steam and lift the paste, creating flakiness.
- Egg
- Binds the dough and adds richness and tenderness.
The step that matters
Enclosing the butter and resting between rolls. The butter must stay fully wrapped and in distinct sheets. If it breaks through or softens into the dough, the layers blend and the pastry loses its flakiness. Resting lets the gluten relax so the paste rolls without tearing or shrinking back.
