Pie Crust

1. Mix flour, sugar, and salt in processor. Add butter; pulse until coarse meal forms. Gradually blend in enough ice water to form moist clumps. Gather dough into ball; divide in half. Form dough into 2 balls; flatten into disks. Wrap each in plastic; chill 2 hours or overnight.

Lamb

1. Heat oven to 425 degrees. Trim excess fat from lamb. In a food processor, make persillade by puréeing olive oil, parsley, garlic, lemon zest and some salt and pepper.
2. Sprinkle lamb with salt and pepper on both sides, then turn so the side that had been on the bone, the one with the more irregular surface, is facing up, with the wider end facing you. Smear the surface of lamb with most of persillade mixture, then fold it in half (there will be a kind of natural hinge, as you’ll see) with persillade on the inside. Save the remaining persillade and set aside.
3. Put lamb in a roasting pan and cook for about 35 to 40 minutes for rare meat, or until an instant thermometer inserted into the thickest part of the meat reads 130 degrees, or, for medium rare, 135 degrees. Let the meat rest for at least 20 minutes for the juices to be redistributed before slicing. (Note: You need about 1 pound of cooked lamb meat for this pie recipe.)

Assembly and baking

1. Preheat the oven to 425°F and prepare two sheet pans lined with Silpats or parchment paper.
2. Roll out the pie dough on a lightly floured surface with a rolling pin. Roll to 1/8-inch thickness and stamp out with a 3-inch square cookie cookie cutter. If there’s dough leftover from each process, re-roll the dough and repeat until you’ve completed the process and count out about 24 squares to make the 1 dozen pies.
3. On half of the pie squares, spread about 1/2 teaspoon of persillade but leave about 1/4-inch border to have room to crimp and seal the pies and top it with a 1/4 teaspoon of cooked lamb. Cover each pie with the unseasoned pie crust and use the tines of the fork, floured and press down firmly around the edges of the pie. Set the pies on the prepared sheet pan with a 1/2-inch space and brush the pies with an egg wash. Sprinkle some large flaked sea salt (I sprinkled dried oregano and sea salt mixture for added flavor).
