In a medium saucepan, melt the butter over medium heat. Add the milk powder and whisk continuously for 3-4 minutes or until it turns brown.
6 Tablespoons unsalted butter, 2 Tablespoons nonfat dry milk powder
Turn off the heat and stir in the chopped pistachios. Set aside to cool to room temperature.
1 cup chopped shelled pistachios*
In a medium bowl, whisk together 1 cup of the heavy cream, granulated sugar, brown sugar, vanilla extract, and almond extract until well combined.
2 cups heavy cream, ½ cup granulated sugar, 1/3 cup brown sugar, 2 teaspoons vanilla extract, ½-1 teaspoon almond extract*
Whisk in the remaining heavy cream and whole milk.
1 cup whole milk
Stir in the cooled pistachio mixture and 1-2 drops of food coloring, if using. Cover the mixture with plastic wrap or foil and refrigerate for 1-2 hours or overnight.

Once chilled, pour the mixture into a pre-frozen bowl or ice cream machine. Follow the manufacturer’s instructions for your ice cream maker.
Secure the paddle and lid, if using a Cuisinart ice cream maker. Churn for 15-20 minutes or until the mixture thickens.
Remove the paddle. Serve immediately for a soft-serve consistency or transfer the ice cream to an airtight container and freeze for an additional 3-4 hours for a firmer texture. Store leftovers in an airtight shallow container in the freezer.
