Italian Pistachio Gelato Recipe

Recipe Type: Ice CreamDessertPistachio
Cuisine: Italian
Yields: 1 quart
Prep time: 20 min
Total time: 1 hr


Ingredients:
4 cups whole milk, divided
3 tablespoons plus 2 teaspoons cornstarch

1 cup superfine sugar
1 teaspoon pure vanilla extract
1 cup Flavor Variation, of your choice (see below)


Preparation:

When in Italy, I learned that one of the main differences in gelato is in the preparation. Gelato is made in a custard form first, heating it up, and then allowing it to cool down before putting in the ice cream maker.
In a small bowl combine 1 cup milk, cornstarch, and sugar. Using a wire whisk, combine the ingredients to form a slurry so that all the cornstarch is dissolved and the mixture is smooth.
In a medium-size saucepan over medium heat, combine the remaining 3 cups milk and the vanilla extract. Stirring occasionally, heat the mixture to almost a boil; stir in the cornstarch mixture and let simmer from 5 to 12 minutes to thicken, stirring constantly. Another important tip is to stir slowly, (do not whisk) which will prevent too much air from being incorporated in the custard and will produces smaller ice crystals.
Remove from heat and transfer the mixture to a bowl. Cover and refrigerate until completely chilled, preferably overnight.
Prior to using the custard mixture, pour the chilled custard through a strainer into a mixing bowl to clear out any clumps that may have formed. Store in the refrigerator until ready to use.

Prepare the Pistachio Cream (see below).
Whisk the prepared chilled Pistachio Cream into the strained and chilled custard. The gelato mixture is now ready for the freezing process.
Transfer the mixture into your ice cream maker and freeze according to the manufacturer's instructions. Either churn your ice cream by hand or by motor. With Gelato, it is best to not process it until it is hard. Instead, stop the ice cream maker at soft serve consistency, then put it in a container in your freezer until hard for a delicate flavor and texture that differentiates it from ice cream.

When the gelato is done, either serve and enjoy (best if eaten and enjoyed immediately as gelato has a shorter storage life than ice cream) or transfer to freezer containers and freeze until firmer.
Makes approximately 1 quart of pistacho gelato.


Pistacho Cream
Pistachio Cream:
1 cup hot water
7 to 8 ounces raw unsalted shelled and hulled pistachio nuts
2 tablespoons superfine sugar
2 teaspoons olive oil

In a medium-size saucepan, bring water to a boil.
Place the pistachio nuts, sugar, and olive oil in a food processor. Blend/process, adding the hot water (1 tablespoon at a time to control the consistency of the cream) until pistachios are a smooth, creamy consistency that blends freely in the blender (I actually used 9 tablespoons of hot water).
NOTE: Stop the processor and scrape down the sides of the bowl several times during this process.
