Position a rack in the center of the oven and preheat the oven to 375 degrees F. Line two or more cookie sheets with parchment paper.
Combine the flour, cream of tartar, baking soda, and salt in a small bowl. Set aside for use in Step 4.
Place the sugar, butter, and shortening in the bowl of an electric mixer fitted with a paddle attachment. Beat on medium speed until creamy. Add the egg and beat until light and fluffy, about 1 to 2 minutes. Scrape down the sides of the bowl as needed to ensure even mixing.
Turn the mixer to low speed and add the orange zest and vanilla extract, followed by the flour mixture. Mix just until the dry ingredients are evenly incorporated.
Stir in the granola, raisins, and chocolate bits
Roll the dough between your palms into 1-inch balls and place about 2 inches apart on the prepared cookie sheets. For the most uniform balls, first portion the dough into 1-inch mounds using a slightly rounded 1 3/8-inch (#70) scoop or about 2 level teaspoons per mound; then roll into perfect balls. Flatten the cookies into 1 1/2-inch disks by gently pressing them with the palm of your hand.
Bake 8 to 9 minutes, or until lightly browned. (If you want to see more spring-y color on top, stud the cookies with additional chocolate bits about midway through baking.) Immediately transfer the cookies to wire racks, using an offset spatula to prevent breakage. Cool completely before storing.
