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 ↓

Ingredients
Directions
Make the dough
In a large bowl, combine the flour and salt.
Cut the butter into small pieces and mix it into the flour until crumbly.
Gradually add ice water, mixing until a dough forms.
Laminate and chill
Knead the dough gently, then roll it out on a floured surface.
Fold the dough several times to create layers, then refrigerate before use.

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
- Butter
- Cold pieces stay separate in the dough and melt into layers that puff and flake when baked.
- Pastry flour
- Forms the dough's structure, giving the layers something to hold them together.
- Ice water
- Binds the flour and butter into a dough while keeping the butter cold and limiting gluten development.
The step that matters
Keeping the butter cold and in pieces. If the butter softens or melts into the flour, it cannot form distinct layers. Cold butter stays solid during rolling and folding, and its water turns to steam in the oven, pushing the layers apart.
