Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Puff Paste
Ingredients
Directions
Prepare the dough
Divide the butter into three parts.
Rub one part into the flour until well mixed.
Stir in the water and form a stiff paste with a spoon.
Place the paste on a smooth surface and roll it out once in each direction.
Laminate
Fold the four ends inwards, then roll it lengthwise and sideways.
Spread half of the remaining butter in small pieces on the paste, sprinkle with flour, fold, and roll as before.
Spread the rest of the butter, repeat the folding and rolling process.
Fold and roll twice more, then let it cool for 10 minutes.
Roll out the paste very thin, and it is ready for use.

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
- Wheat flour
- Forms the structure of the paste that holds the layers together.
- Sweet butter
- Creates separate layers that puff apart as the pastry bakes.
- Water
- Combines with the flour to form a stiff, workable paste.
The step that matters
Spreading the butter and folding into layers. Butter must stay in distinct pieces and layers between folds; if it softens and blends into the dough, the layers will not separate and the pastry will not puff.
“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.
