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
Make the dough
Rub ½ pound of butter into 1 ¼ pounds of sifted flour in a bowl using your hands.
Mix in ½ pint of spring water and knead the dough well.
Let the dough rest for 15 minutes.
Laminate and chill
Roll the dough out thinly.
Place ¾ pound of butter in small pieces on the rolled dough and sprinkle with a little flour.
Fold the dough over the butter, then roll it out thinly three times.
Chill the dough in a cold place for about 1 hour.

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
- Flour
- Forms the gluten network that gives the dough its structure and sheet-like strength.
- Butter
- Forms separate layers that turn to steam in the oven, lifting the pastry into flaky sheets.
- Spring water
- Hydrates the flour so gluten can develop and the dough becomes elastic enough to roll.
The step that matters
Folding and rolling the butter layers. If the butter breaks through the dough or warms and softens into it, the layers merge and the pastry loses its flakiness. Keeping the dough cold between rolls keeps the butter in distinct sheets.
