Preheat oven to 350°
In a food processor, grind pistachios to small and chopped, but not a powder.
In a stand mixer, beat sugar and butter till well combined. The color should be a light and pale.
On a slow speed, mix in vanillina, ricotta, pistachios, and egg.
In a separate bowl, mix the dry ingredients - flour, panedeangeli, and if using salt.
The dough will start to form and once all is combined, swipe sides, mix once more, and then start to form cookies.
Using a tablespoon, measure out a piece of dough and then roll it into a ball and place on a parchement lined baking sheet. **The smaller the cookies, the more cookies youll get, but if you want to speed up make them larger. **If you run your hands under warm water before rolling, the balls will be smoother, you would have to do it every so often because the dough is sticky! Bake in preheated oven for 15-17 min (timing depends on your oven, mine took about 17 minutes the goal is for the bottom to be golden brown but the tops to be soft.)
