  2. Mix in enough water to make a stiff paste with the flour.

Laminate

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg white
Its proteins trap air when beaten, adding lightness to the paste.
All-purpose flour
Forms the gluten network that gives the paste its stiff, stretchable structure.
Butter
Forms separate fat layers between the dough sheets, helping create flakiness when baked.

The step that matters

Rolling the paste very thin. Thin sheets with layers of butter between them let steam separate the layers as it bakes, so an overly thick paste gives a dense result instead of flakes.
