Crostata with Pecan and Blueberry Pie Filling

* The memory card of my camera just crashed and that's the only picture I could recover of the crostata right before getting in the oven.

A crostata is a dessert that is filled with jams or fruits and its sweet crust is folded inward at each edge. It gives the tart a more artisanal, which means rustic in French, and free-form look than other regular pies.

I made the dough with polenta to give it a more crumbly texture and flavored it with star anise. I used fresh ginger and Meyer lemon for the filling in addition to the blueberries.
