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 paste that holds the layers together.
Butter
Creates flaky layers as it stays solid between folds and melts in the oven.
Egg
Adds richness and helps bind the dough into a smooth paste.

The step that matters

Folding the dough with butter layers. Repeated rolling and folding spreads the butter into thin sheets between layers of dough. If the butter softens too much or melts into the dough, the layers merge and the pastry loses its flakiness.
