The lastest contest at Food52 is all about tarts, Your Best Tart to be exact, I have to say that making pies and tarts is something I love doing,  I put my thinking cap on because I wanted to come up with a recipe that was a little different and creative.  Buttery pastry with an assortment of fillings whether sweet or savory is comfort food at it’s best IMHO. I was already in the cream or curd mode after making the scones so I whipped up another batch just using oranges and tangerines, it has substance from the addition of cream cheese which give a little tang also, the crust is adapted from Martha Stewarts recipe for Pate Sucré.  The combination of chocolate and orange has always been one of my all time favorite flavor combinations so I covered the orange cream with a ganache gently flavored with orange thanks…
