Preheat oven to 400 F.
In the bottom of a large bowl, combine the flour, salt and sugar. Work the butter into the flour with your fingertips or a pastry blender until mixture resembles a coarse meal and the largest bits of butter are the size of tiny peas.
Add 1/4 cup cold water and stir with a spoon or flexible spatula until large clumps form. Use your hands to knead the dough together, right in the bottom of the bowl. If necessary to bring the dough together, you can add another tablespoon of water.
Wrap dough in a sheet of plastic wrap and refrigerate for at least one hour, or up to 48 hours, or you can quick-firm this in the freezer for 15 to 20 minutes.
On a floured counter, roll the dough out into a 12 to 13-inch circle shape. Fold dough gently in quarters without creasing and transfer to a 9 1/2-inch standard pie plate. Unfold dough and trim overhang to about 1/2-inch. Fold overhang under edge of pie crust and crimp decoratively.
Freeze for 15 minutes, until solid. Dock all over with a fork. Coat a piece of foil with butter or nonstick spray and press tightly against frozen pie shell, covering the dough and rim and molding it to fit the shape of the edges. Bake for 20 minutes, then carefully, gently remove foil. If any parts have puffed, just press them gently back into place. Patch any tears or cracks with reserved dough scraps.
In a large non-stick pan add ground beef, onion, garlic, salt and flour. Sauté on medium heat for 3-5 minutes until beef is browned.
Stir in pickle juice, liquid smoke, milk, chopped pickles, and shredded cheese. Spoon mixture into the prepared pie crust.
Bake in preheated oven for 20 minutes. Let rest for 30 minutes before slicing and serving. Serve topped with sliced pickles and dollop of sour cream.
