Substitutions in Baking

Last night I made Mini Pies and they turned out great and wanted to share the recipe and pictures.  Summer has been so much fun and I am learning the more I bake the more I love it!
It was a bit of an adventure regarding ingredients.  I began with the crust which calls for 2 cups all-purpose flour, 1/2 teaspoon of salt, 3/4 cup sliced butter, and 4 tablespoons of water.  Depending on what I am making, I try and do half all-purpose flour and half whole wheat flour.  So I proceeded to do that with the pie crust.  Although after measuring out the flours I realized that it was not whole wheat flour that I measured but rather wheat bran.  I called my mother and she said to just use what I measured and it would turn out fine.  So that is what I did.  I proceeded to make the crust and then put it in the fridge for 30 minutes.
While the crust was in the fridge, I made the pie filling.  My original plan was to make apple pie.  But then I saw that we only had one apple so that would not work.  I had a recipe for filling which included raspberries and blueberries which I had but it called for cornstarch which I did not have.  I looked up on the internet and saw that I could use flour instead if I use double the amount.  So for the filling I used 3/4 a bag or frozen raspberries, 1/2 bag of frozen blueberries, 1/4 cup sugar, 1 tablespoon of lemon juice, and 8 tablespoons of flour.  I mixed it all together.
I used mini pie dishes that we had but you could also used cupcake pans.  I rolled the crust out and cut them into the correct size circles.  Then I filled with pie filling and covered them with another circle with a slit in the top.  Right before I put them in the oven, I brushed egg on the tops of them.  I cooked them for 25 minutes on 375 degrees.
They turned out VERY good!  I like using whole wheat flour because it gives a lot more flavor to the baked goods and the wheat bran did the same.  If I made these again I will use the wheat bran again just because they turned out with a lot of added flavor(and fiber!).  We had them with Trader Joe's vanilla ice cream and whip cream.  They were great!
Here are some pictures!!
