Combine the pancake mix and the cake flour and set aside. If using butter, melt it and set it aside.
Make a well in the dry ingredients and pour the oil in the center. Add some water, a little a time, into the dry ingredients while shaping the dough into a ball with a spatula.
Wrap the dough in plastic wrap. Chill in the refrigerator for as long as possible. (Cut the plastic wrap one size larger than the tart pan, since you will use it later when rolling out the dough.)
Open the plastic wrap and cover the dough with another piece of plastic wrap. Roll the dough with a rolling pin to match the size of the tart pan. (This technique eliminates the need to dust the working surface.)
Take off the top piece of plastic wrap, flip the crust over and into the tart pan with the bottom piece of plastic wrap attached. Shape the dough by pressing it into the tart pan over the plastic wrap to shape the crust. Cut off the excess edges with a rolling pin.
Slowly remove the plastic wrap. Pierce several holes in the bottom and grooves of the crust.
If you are blind-baking the crust, bake it at 180℃ for 10-30 minutes. (Adjust the temperature to the baking time or for the type of tart). If you have pie weights, it will turn out looking even better.

Story Behind this Recipe
I made this crust when I did not have tofu to make the "Easy Tofu Tart" crust. I was not sure if I wanted to share this recipe, but I do want to save it as a recipe.
I recommend using this crust for a tart with the filling that needs pre-baking, such as custard cream or for a tart that you eat as a meal; though, this crust goes well with anything. You can grease the tart pan with some butter, but if you dust the tart with some flour and press it onto the tart pan, it comes out easily. You can also use margarine, if you are going to eat it at home.
