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 in enough water to make a very stiff paste with the flour.
Laminate the butter
Roll the paste very thin.
Place small bits of butter on the paste and dredge with additional flour.
Roll it up tightly, then roll it out again.

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
- Fine flour
- Forms the stiff paste that gives the dough its structure.
- Egg white
- Beaten to a froth, it adds lightness and helps bind the dough.
- Butter
- Layered through the rolled dough, it creates flaky, tender layers as it melts during baking.
The step that matters
Rolling the butter into the paste. Butter must stay in small, cold pieces spread through the dough. If it softens or melts into the paste while rolling, the layers merge and the pastry loses its flakiness.
