Crust
Dice the butter and return it to the refrigerator while you prepare the flour mixture.
Place the flour, salt, And sugar in the bowl of a food processor fitted with a steel blade and pulse a few times to mix.
Add the butter and leaf lard. Pulse 8 to 12 times, until the butter is the size of peas.
With the machine running, pour the ice water down the feed tube and pulse the machine until the dough begins to form a ball.
Dump out on a floured board and roll into a ball.
Wrap in plastic wrap and refrigerate for 30 minutes.
Cut the dough in half. Roll each piece on a well-floured board into a circle, rolling from the center to the edge, turning and flouring the dough to make sure it doesn't stick to the board.
Use round cookie cutters (3 inches is a good size) to make your pies. Each pie needs 2 circles-a top and bottom.
On the bottom, place some fluff, mini marshmallows, one square of chocolate and a sprinkle of graham cracker crumbs.
Brush edges with egg wash.
Top with a second circle and use a fork to crimp the edges.
Brush with egg wash, make a few slits and bake on a parchment lined cookie sheet at 400 degrees for approx 14 mins until browned.
Serve with a drizzle of melted chocolate, if desired.
