Why does lemon pie use shortcrust pastry?

* Texture: Shortcrust pastry provides a crisp, crumbly texture that contrasts nicely with the smooth, tangy filling. The flaky layers add an interesting textural element to the pie.

* Flavor: The subtle buttery flavor of shortcrust pastry complements the citrusy notes of the lemon filling without overpowering it.

* Stability: Shortcrust pastry is sturdy enough to hold the weight of the lemon filling without collapsing. It also provides a barrier to prevent the filling from soaking into the crust and becoming soggy.

* Tradition: Shortcrust pastry is a classic choice for pie crusts, and it has been used in lemon pie recipes for generations. The familiar taste and texture contribute to the overall nostalgic appeal of the dessert.

While other types of pastry can be used for lemon pie, shortcrust remains the most popular choice due to its balance of texture, flavor, and practicality.
