Peach Homemade Puff Pastry Crostata

From Claudia's kitchen @What's Cookin' Italian Cuisine
2 cups flour
16 Tablespoons unsalted butter
2/3 cup ice cold water
pinch of salt

Mix 1/4 cup of flour with 14 tablespoons softened butter to make a smooth paste. Shape into a square approximately 1/2 inch thick. Cover and refrigerate 30 minutes. In another bowl mix the cold water, 2 tablespoons of butter, and the remaining 1 3/4 cup of flour and a pinch of salt. This will be an elastic, shiny dough. Knead for about one minute. Cover and refrigerate 30 minutes. Refrigerating the dough makes this easier to roll the dough without breaking it. On a lightly floured board, roll out the shiny dough 1/4 inch thick. Place the butter dough square onto the shiny dough and wrap the ends of the shiny dough to enclose the butter dough in an envelope .Roll out the dough envelope to 1/4 inch thickness and fold in thirds like a business letter.
Roll again in the opposite direction and fold in thirds again. Refrigerate 30 minutes and repeat the process twice for a total of six times of folding in the process. This will be making many of hundreds buttery layers. Cooling the dough is very important step. After folding the dough the sixth time, refrigerate the dough once more, and then it will be ready for use for any recipe that requires puff pastry. Tip: The oven must be preheated to a high temperature,  400 or as high  450, when the dough is placed in the oven. If the oven is not hot, the butter will melt and the moisture will evaporate before steam can form to separate the layers. You will end up with a tough non-flaky crust and Crostata.
Peach or any other fruit filling:
I use four peaches peeled and cubed...throw the pit away
2 heaping tablespoons of peach jam, apricot or pineapple ( depending on the type of fruit, use coordinating jam)
1 teaspoon of wondra flour
 optional pinch of cinnamon
Mix all together the flour will thicken this mixture perfectly
Roll out your dough 1/4 inch thick cutting the edges to make it round.
Pile the fruit in the middle, fold the edges towards the middle leaving the fruit center showing, but the dough tucked around it. Dot with butter.
Bake in a hot oven on 400 degrees or higher till browned nicely.
