One of my first pie making attempts was an Apple Pie. It tasted really good. But it was really runny! After this experience I read a lot of apple pie recipes The trick to making an apple pie with out all of the juice soaking up the bottom crust and running all over the plate when you take out a slice is two easy steps.
First, blind bake the crust before you put any of the filling in. This makes it so the juice from the apples doesn't soak into the crust so easily.
The second trick is to precook the apple mixture in a sauce pan. This way you can drain out all of the extra juice before you put the apples in the pie.
I just love it when I can read up on recipes and figure out how to fix what went wrong. That's what makes the process of learning pie baking so fun!
