Make the crust by mixing the flour, salt and sugar in a food processor.
Add butter and pulse
Add ice water as the processor is mixing until the dough just comes together.
Remove form into a flat disc, wrap in plastic, and refrigerate for 1 hour.
Meanwhile toss the cranberries, pear slices, cinnamon and sugar in a large bowl.
Preheat oven to 350 degrees
After the dough has been refrigerated for one hour remove and roll out into a 1/4 to 1/8 inch thick round shape. It doesn't have to be perfect.
Place the dough on a baking sheet and then pile up the filing in the middle of the dough.
Then fold over the outside edges, about 2 inches.
Brush with the egg wash and bake for about 1 hour at 350 degrees.
