Creating Creamy Homemade Pistachio Pudding is straightforward if you follow these simple steps:

1. Prepare Pistachios: In a food processor, blend the shelled pistachios until finely ground. Set aside a tablespoon of ground pistachios for garnishing later.
2. Combine Dry Ingredients: In a medium saucepan, whisk together the granulated sugar, cornstarch, and salt.
3. Add Milk: Gradually whisk in the whole milk until the mixture is smooth and free of lumps.
4. Cook the Mixture: Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens and bubbles. This should take about 8-10 minutes.
5. Add Flavor: Once thickened, remove the saucepan from heat. Stir in the ground pistachios, butter, and vanilla extract. If desired, add a few drops of green food coloring to enhance the pudding’s color.
6. Cool the Pudding: Pour the pudding into a bowl or individual serving dishes. Cover with plastic wrap, pressing it directly onto the surface of the pudding to prevent a skin from forming.
7. Chill: Allow the pudding to cool at room temperature for about 30 minutes, then transfer it to the refrigerator. Chill for at least 2 hours, or until fully set.
8. Serve: Once chilled, give the pudding a good stir before serving. Top with whipped cream and sprinkle with reserved ground pistachios for added texture.
