Pistachio gelato, made properly, relies upon nothing but pistachio paste, milk, cream, sugar, vanilla, and salt for its flavor and color. That's why true pistachio gelato isn't Frankenstein green. Spoons at the ready!
Mix the 1 cup granulated sugar, 1 teaspoon xanthan gum, andapinch of saltin a small bowl.
Pour the 2 cups whole milk and the sugar mixture into a saucepan and bring to a simmer over medium heat.
Stir continuously until the sugar dissolves completely, 2 to 3 minutes.
☞ TESTER TIP: Don’t let the mixture boil.
Slide the saucepan off the heat and whisk in the 1 cup heavy cream.
Add the ¾ cup pistachio paste and 1 teaspoon vanilla extract.
Whisk until smooth. (I use an immersion blender for this, but you can also use a canister blender.)
Cover the bowl and slide it into the fridge to chill for at least 4 hours or, for better flavor and texture, overnight (8 to 12 hours).
Churn the gelato
Pour the chilled pistachio gelato base into an ice cream maker and churn according to the manufacturer’s instructions until it reaches a soft-serve consistency. Add the 1/2 to 3/4 cup coarsely chopped pistachios if using.
Transfer the ice cream to an airtight container and freeze until firm.
Remove the gelato from the freezer 10 minutes before serving. Gelato is traditionally served at a slightly warmer temp that American ice cream.
Notes
Chilling—Chilling the base overnight allows flavors to deepen and ensures a smoother texture.
Blend—Use an immersion blender or canister blender to ensure a silky smooth texture with no graininess.
Stabilizer—Xanthan gum prevents ice crystals for a dense, creamy texture.
Wait—Allow the gelato to sit at room temperature for 10 to 15 minutes before serving for the best texture and flavor.
Dietary—This recipe is suitable for gluten-free diets.
