Step 1: Preheat the oven to 350 degrees. Butter a large cookie sheet. In a small bowl whisk the egg with vanilla until combined.
Step 2: In a food processor fitted with the steel blade, pulse the pecans until they are finely chopped. Add 3/4 cup powdered sugar, flour and salt, and pulse again. Scrape down the sides of the bowl with a spatula if necessary.
Step 3: Drop in the butter and shortening chunks, and pulse a couple of times. Add the egg/vanilla mix and pulse again, just until the mixture starts to come together. Roll the dough into 1 to 1 1/2-inch balls with your hands.
Step 4: Plce the balls on the baking sheet, spacing them 1 inch apart. Using your finger press down the bakk just slightly. Bake until the cookies are golden brown, about 12-15 minutes. You may need to bake two batches.
Step 5: Immediately roll the hot cookies in confectioners sugar. Place on a rack. Cool completely then roll the cookies for a second time in the sugar.
