Mini Blueberry Strawberry Pies

My sourdough starter needed refreshing, and I had frozen the leftover blueberries and strawberries before traveling last week. It was time for Mini Blueberry Strawberry Pies with a sourdough crust (or pate brisee.)

Ingredients:

• 1 cups all purpose flour (125 grams)
• 1/2 tsp salt 
• 1 TBSP powdered sugar
• 1 sticks cold butter, cut into 1/4" cubes
• 1/2 cup sourdough starter (4 ounces)
• 3 to 4 cups blueberries
• 1 to 2 cups strawberries, diced into small pieces
• 1/2 cup white sugar
• 1/4 cup cornstarch
• Optional - zest from 1 orange

Instructions:

1. In a food processor, whisk together the flour, salt, and sugar with the metal blade.
2. Drop the butter around the flour, and pulse together in a few short bursts to get some smaller chunks.
3. Scoop in the sourdough starter, and pulse together in a few short bursts until dough mostly comes together.
4. Form the dough into 1" thick disk or brick, wrap with plastic wrap, and chill in the refrigerator for at least 30 minutes.
5. Preheat the oven to 400 degrees about 15 minutes before baking the pies. Lightly spray six 4.5' diameter in a tartlet pan with cooking spray.
6. Divide pie dough into 6 equal pieces (mine were about 2 ounces each)
7. Roll out each piece, and fit each piece into a mini pie pan as a crust.
8. Place pie crusts in tartlet pan  in freezer for 10 minutes.
9. Mix 5 cups of blueberries and diced strawberries with 1/2 cup sugar and 1/4 cup cornstarch.
   (Mix in the orange zest if using.)
10. Let fruit miz sit for a few minutes.
11. Place 3/4 a cup or so berry mixture in each pie crust.
12. Put the pan on a rimmed baking sheet and place in the pre-heated oven.
13. Bake for 35 to 40 minutes in oven until the crust looks done the filling is bubbling
    (Watch the crust does not get too done.)
14. Cool pan on a cooling rack for an hour or so.
    
    

Carole's Notes:

The mini pies were tasty. However, I think the orange zest made them seem less berry, so I will probably skip it next time.

I made a half recipe of this crust http://carolelikesroundfood.blogspot.com/2016/05/loquat-cherry-pie-with-sourdough-pate.html with slightly different mixing directions.
