Lightly grease your pie plate and preheat the oven to 400 degrees.
In a medium-size bowl, mix together the 1 1/4 cups flour with the salt, onion powder, chipotle, and sugar.
Cut the 1/3 cup of cold butter into cubes and add it to the flour mixture. Using a pastry blender, cut the butter into the flour until it resembles coarse crumbs the size of peas.
Add in the egg yolk and 6 tbsp of ice water. Mix together with your hands or spoon until the dough just comes together. Don't over mix or your crust will be hard and tough.
Generously flour your countertop and place the pie dough in the middle of it. Also, flour the top of the dough and your rolling pin. Roll out the dough in a circle shape big enough to cover your pie plate with dough hanging over the edges, make sure to continue to flour underneath it so it doesn't stick to the counter.
Once the dough is rolled out, carefully pull the dough up over the rolling pin, folding it in half over itself with the rolling pin keeping the two halves from touching. Gently slide the dough over the top of your pie plate unfolding as you go until the dough is fully covering it.
Make sure the pie dough is laying against the bottom and side of the pie plate. Cut off any extra dough that is hanging over the edges. Using a small cookie cutter, cut pieces out of the remaining dough to make your pie crust. Egg wash the crust area and layer the cookie-cutter pieces all the way around, then egg wash those pieces as well.
After you are done with the crust, line the inside of the pie dish with parchment paper and fill it with your pie weights, dried rice, or beans. Quiche is very wet, so it helps to blind bake the crust before filling it with the egg mixture.
Bake the crust on the middle rack of your oven for 10 minutes. When the 10 minutes are up, bring it out of the oven and set it on top of the stove while you finish the filling.
