Help! My crust looks cracked after par-baking! What happened? Do I need to scrap the crust and start over? ver?

Either fix will work fine. Fortunately, the filling will cover the evidence and no one need ever know about the repairs that lie beneath. The pie will be good enough that they won't care anyway.

You can also mix flour and a bit of water into a thick, spackle-like paste, carefully spread it over the cracks, and continue baking for a few minutes until the paste dries!

I'm no expert baker, but I have patched my par baked crusts with leftover pie dough and it worked out fine.
