I found this in October's BHG. It's not a pastry cream base but sounds mighty good and would work as a puff filling. I'm going to try it with my homemade cannoli shells which by the way look exactly like the ones in the picture. oops, sorry, the link doesn't work. I'll just post the recipe, in my own words. Pumpkin Pistachio Filling 1/2 an 8oz carton mascarpone cheese 3/4 C powdered sugar 3/4 C canned pumpkin 1/2 C ricotta cheese 1 tsp. pumpkin pie spice 1/2 C chopped roasted pistachio nuts 1/2 C whipped cream Mix together mascarpone cheese, sugar, pumpkin, ricotta & spice. Stir in 1/4 C of the nuts. Whip cream & fold into the pumpkin mix. I would probably omit the nuts.
