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

What each ingredient does

Butter
Rubbed into the flour to coat particles and keep the pastry short and tender.
Flour
Forms the structure of the pastry once bound with liquid.
Egg yolk
Adds richness and helps bind the dough together.
Cold water
Moistens the dough so the flour and fat hold together into a paste.

The step that matters

Rubbing the butter into the flour. If the butter warms and melts instead of staying in small pieces, the pastry becomes greasy and tough rather than crumbly and tender. Keeping the mixture cool preserves the flaky, short texture.
