We missed them especially while doing the things we've done every Christmas for 30 years but I felt so lucky to have had my sister's pixelated face across the tree from me. Very 2013.
She writes the backstory: The sweet-and-sour filling in this tart is composed of only three ingredients - paper-thin slices of lemon (rind and all), sugar, and eggs - a fitting expression of the Shakers' loathing of wastefulness. Baked in a pie shell, the dessert is commonly known as Ohio lemon pie, so named for the Shakers who eventually made their home in the state.
Shaker Lemon Tart
from Martha's American Food: A Celebration of Our Nation's Most Treasured Dishes, from Coast to Coast
2 large meyer lemons, preferably organic, washed well
2 cups sugar
Basic pie dough (recipe below)
Flour for dusting
4 large eggs, lightly beaten
1. Cut lemons crosswise into paper-thin rounds using a mandoline or a very sharp knife; discard ends and seeds. Place lemon slices in a medium nonreactive bowl, and add sugar; toss to coat. Cover with plastic wrap and let stand at room temperature overnight.
2. Roll out dough on a lightly floured work surface to 1/8 inch thick. Fit round into tart pan and push rolling pin across the top to remove excess dough. Place tart pan on baking sheet; freeze dough until firm, at least 30 minutes or up to 1 day (covered with plastic wrap).
3. Preheat oven to 450 F, with rack in lower third. Add eggs to lemon mixture and stir to combine. Pass through a fine sieve into a medium bowl. Dividing evenly, pour filling into tart shell, then arrange lemon slices on top.
4. Bake tart on rimmed baking sheet for 15 minutes. Reduce heat to 350 F; bake until filling is set and beginning to brown on top, about 20-25 minutes more. Let cool on a wire rack 10 minutes, then transfer to a rack let cool completely.
3 cups all-purpose flour
1 teaspoon salt
1 tablespoon sugar
1 cup (2 sticks) plus 2 tablespoons col unsalted butter, cut into small pieces
1/4 to 1/2 cup ice water
1. Pulse together flour, salt, and sugar in a food processor to combine. Add butter; pulse until mixture resembled coarse crumbs with some larger pieces remaining, about 10 seconds. Evenly drizzle 1/4 cup ice water over mixture. Pulse until mixture just begins to hold together (it should not be wet or sticky). If dough is too dry, add up to 1/4 cup more water, 1 tablespoon at a time, and pulse to combine.
2. Divide dough in half. Wrap each in plastic; shape into disks. Refrigerate until chilled, at least 1 hour or up to overnight. (Dough can be frozen up to 1 month; thaw overnight in refrigerator before using.)
