Ingredients
Pistachios
- 2 cups shelled unsalted pistachios (plus optional ½ cup coarsely ground)
Milk Mixture
- 2½ cups whole milk
- 1½ tablespoons corn starch (use only if needed)
- ⅔ cup sugar (adjust to taste, typically ½ cup + 2 tablespoons)
- A pinch of salt
- ½ teaspoon pistachio extract (optional, or 1 drop almond extract plus 2 tablespoons pistachio oil)
Cream
- 1 cup heavy cream
Instructions
- Prep the pistachios: Boil 4 cups of water and add 2 cups of shelled pistachios. Simmer for 2 minutes, then drain and rinse under cold water. Cool the pistachios and rub between kitchen towels to remove skins.
- Blend the pistachios: Using a high-speed blender or food processor, blend the 2 cups of pistachios with 2 cups of whole milk until smooth, about 2 minutes. Cover and refrigerate overnight to develop flavor.
- Strain the mixture: Pour the chilled pistachio-milk mixture through cheesecloth or a nut bag to remove any solids. Stir occasionally to aid straining. This step can be skipped if your blender produces a very smooth paste.
- Thicken the nut milk: Place the pistachio-milk in a large saucepan over medium-high heat, stirring constantly without boiling. Dissolve 1½ tablespoons of corn starch in ½ cup plain milk, then lower heat and whisk this mixture into the pot. Simmer for about 6 minutes until a thin custard consistency is reached. Remove from heat and cool over an ice bath.
- Add remaining ingredients: Whisk in the sugar, remaining milk (if unused for thickening), salt, and flavoring (pistachio extract or almond extract plus pistachio oil). Then fold in the heavy cream.
- Chill the mixture: Refrigerate the gelato base for several hours or overnight to allow flavors to meld and mixture to cool thoroughly. Alternatively, use an ice bath to chill faster.
- Freeze the gelato: Pour the chilled base into an ice cream maker and churn according to the manufacturer’s instructions. Optionally, add the coarsely ground pistachios toward the end of churning for texture.
Notes
- Removing the pistachio skins helps achieve a smooth and vibrant green gelato.
- If you don’t have pistachio extract, almond extract with pistachio oil creates a great flavor substitute.
- The corn starch thickening step is optional but improves the gelato’s creamy texture.
- Chilling the mixture overnight enhances the flavor and texture before freezing.
- Adding chopped pistachios during churning gives your gelato a delightful crunch.
