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 and provides the structure of the dough.
Butter
Creates layers that separate the dough, giving a light, flaky texture when baked.
Egg white
Adds structure and lightness to the paste through its proteins.

The step that matters

Rolling the butter in evenly. Butter pieces must be spread and folded into the dough in even layers. If they melt into the paste or are unevenly distributed, the layers will not separate, and the pastry will be dense rather than light and flaky.
