Creating Cannoli Bites is straightforward if you follow these clear steps:

1. Make the Dough: In a medium bowl, combine flour, granulated sugar, cocoa powder, and cinnamon. Mix well.
2. Add Butter: Incorporate the softened butter into the flour mixture until crumbly.
3. Add Egg Yolk and Wine: Stir in the egg yolk and white wine (or apple cider vinegar) until a dough forms. If the dough is too dry, add an additional tablespoon of wine.
4. Knead Dough: Knead the dough on a lightly floured surface for about 5 minutes. Wrap in plastic wrap and let it rest for at least 30 minutes.
5. Prepare the Filling: In another bowl, combine ricotta cheese, powdered sugar, and vanilla extract. Mix until smooth. Fold in chocolate chips.
6. Roll out the Dough: After resting, roll out the dough to about 1/8-inch thickness. Use a round cookie cutter (or a glass) to cut out circles of dough.
7. Shape the Shells: Wrap each dough circle around a cannoli tube, sealing the edges with a bit of water.
8. Heat the Oil: In a deep frying pan, heat vegetable oil to 350°F (175°C).
9. Fry the Cannoli: Carefully place a few shell tubes into the hot oil. Fry for about 2-3 minutes or until golden brown, turning occasionally.
10. Cool the Shells: Remove the fried shells and place them on paper towels to drain excess oil. Once cool enough to handle, carefully slide them off the tubes.
11. Fill the Cannoli: Using a pastry bag or spoon, fill each shell with the ricotta mixture.
12. Garnish: Sprinkle with chopped pistachios if desired and dust with powdered sugar before serving.

By following these clear steps, you’ll produce an incredible batch of Cannoli Bites that will impress anyone fortunate enough to taste them!
