Can I make the pie crust ahead of time?
Yes. Wrap the dough disks in plastic and refrigerate up to 2 days, or freeze up to 3 months. Thaw in the refrigerator before rolling.
Why use whole sliced lemons instead of juice?
Whole sliced lemons provide natural pectin and rind oils that create the signature tender-crisp texture and complex citrus flavor characteristic of Shaker pie.
How thin should the lemon slices be?
Slice lemons 1/8-inch thick using a sharp knife or mandoline. Thinner slices ensure the rind softens during baking while the filling sets properly.
What indicates the pie is done baking?
The crust should be deep golden brown and the filling will bubble slightly at the edges. The center may still jiggle slightly when gently shaken—it sets as it cools.
Can I use regular unsalted butter instead of European-style?
Yes, though the crust will be slightly less tender and flavorful. European butter (82-86% butterfat) creates superior flakiness compared to standard butter (80% butterfat).
