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 ↓
Light Paste for Tarts and Cheesecakes
Ingredients
Directions
Make the dough
Beat the egg white to a strong froth.
Mix the froth with enough water to make a stiff paste with the flour.
Roll the paste very thin.
Laminate with butter
Dot one-third of the butter in small pieces over the paste.
Dredge with some reserved flour and roll it up tightly.
Roll it out again and repeat with the remaining butter.

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 structure of the dough and, with water, the stiff paste that holds the layers.
- Butter
- Stays in separate layers during rolling, creating flaky texture as it melts and steam lifts the dough.
- Egg white
- Whipped to a froth, it adds air and light texture to the paste.
The step that matters
Roll the paste very thin. Thin sheets separated by butter layers let the dough bake into many flaky leaves. Thick paste produces a dense, less flaky crust.
