Chocolate Walnut Tarts

I made these delectable Chocolate Walnut Caramel tarts for my friend's birthday: He is the kind of guy who likes Tarts!
I used to make this recipe all the time when I worked for Pastry Chef Chris Draa at Wente Vineyards in Livermore California. That was my first pastry job! Chef Draa later contributed the recipe in a Livermore Winery cookbook entitled "Cooking a Honker". We served the tart at the restaurant with chocolate and caramel sauces on the plate, and a dollop of Chantilly Cream.
The tart is regular tart dough (I love tart dough! So tender! So crisp! So endlessly forgiving and versatile!) filled with Walnuts and huge chocolate chunks, and a rich caramel sauce poured over. There are just enough eggs in the caramel to solidify the tart into a rich gooey candy-like confection.
We used to steal a broken piece, cut it into bite sized morsels, and store it on a plate in the reach in for instant sugar-shock snacking.
