What each ingredient does
- Flour
- Provides the structure that holds the crust together.
- Butter
- Adds fat that keeps the crust tender and flaky.
The step that matters
Adding the cold water. Adding too much water develops gluten, making the crust tough, while too little leaves it crumbly and unable to hold together. Cold water keeps the butter solid, which helps create flaky layers.
