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 pastry once bound with liquid.
- Butter
- Rubbed into the flour to create a tender, crumbly texture by coating flour particles.
- Egg yolk
- Adds richness and helps bind the dough together.
- Sugar
- Adds sweetness and gentle browning to the finished crust.
- Baking powder
- Provides a small amount of lift so the pastry is not dense.
The step that matters
Rubbing in the butter. If the butter is rubbed in too coarsely or warms up, it will not coat the flour evenly, and the pastry can turn tough or greasy. Working the butter in until very fine keeps the crust short and crumbly.
