Maple Syrup Sugar Pie

Directions

1. 1
   Preheat oven to 350 degrees F (175 degrees C).
2. 2
   Chop vegetable shortening into flour in a bowl with a pastry cutter until the mixture resembles coarse crumbs. Whisk 1 egg with cold water and vinegar in a measuring cup. Use your fingers to make a well in the center of the flour mixture and pour about half the egg mixture into the well; mix the liquid ingredients into the flour mixture. Mix remaining half of egg mixture into dough, stirring just until combined.
3. 3
   Roll dough into an 10-inch circle on a floured work surface and fit the pie crust into the bottom of an 8-inch pie dish. Trim and flute the edges of the crust.
4. 4
   Whisk maple syrup, 2 eggs, sweetened condensed milk, and brown sugar together in a bowl until brown sugar has dissolved. Pour filling into crust.
5. 5
   Bake in the preheated oven until the filling is set and small spots of sugary crust form on top of the filling, about 45 minutes. Chill until cold and firm, 5 to 6 hours, before serving.
