2-Strain the ricotta cheese by lining a strainer with cheesecloth and refrigerating for several hours or overnight to remove excess moisture.

3-Sift the powdered sugar to avoid lumps, then blend the strained ricotta and pistachio paste in a mixer on medium-high speed for about 30 seconds.

4-Gradually add the sifted powdered sugar and mix on low speed until combined, which helps achieve that perfect creamy texture.

5-Finally, add the vanilla extract and beat on medium-high for a few minutes until the filling is light and fluffy this step makes all the difference.

6-Grind the pistachios finely but not to a powder to retain a crunchy texture, then chill the filling in the refrigerator for at least 30 minutes for improved consistency.

7-Carefully fill each cannoli shell with the pistachio mixture using a piping bag or spoon to avoid breakage, doing this just before serving to prevent sogginess.

8-Garnish the ends with chopped pistachios or a dusting of powdered sugar for an attractive finish, and optionally dip the shell ends in melted chocolate or crushed pistachios and allow to dry.
