Ingredients
  

Ice Cream Base

  • 2 cups heavy cream
  • 1 cup whole milk
  • ¾ cup granulated sugar
  • 4 large egg yolks
  • 1 teaspoon vanilla extract
  • ½ teaspoon black walnut extract optional, but enhances flavor
  • Pinch of salt

Black Walnuts

  • ¾ cup black walnuts chopped
  • 1 tablespoon butter for toasting the walnuts

Instructions
 

Step 1: Toast the Black Walnuts

  • Preheat your oven to 350°F (175°C).
  • Spread the chopped black walnuts on a baking sheet.
  • Toast for 5–7 minutes, stirring occasionally until fragrant.
  • Remove from the oven and toss with 1 tablespoon of melted butter for extra richness. Set aside to cool.

Step 2: Prepare the Custard Base

  • In a medium saucepan, heat the heavy cream, whole milk, and half of the sugar over medium heat. Stir occasionally until the mixture begins to steam (do not let it boil).
  • In a separate bowl, whisk the egg yolks and remaining sugar until pale and slightly thickened.
  • Slowly temper the eggs by adding a small amount of the hot cream mixture while whisking constantly.
  • Pour the tempered egg mixture back into the saucepan and cook over low heat, stirring continuously until it thickens enough to coat the back of a spoon (170–175°F / 77–80°C).

Step 3: Chill the Custard

  • Remove from heat and stir in vanilla extract, black walnut extract (if using), and a pinch of salt.
  • Strain the custard through a fine-mesh sieve into a clean bowl to remove any cooked egg bits.
  • Let it cool at room temperature for 30 minutes, then cover and refrigerate for at least 4 hours (or overnight).

Step 4: Churn the Ice Cream

  • Once chilled, pour the custard into an ice cream maker and churn according to the manufacturer’s instructions (usually 20–25 minutes).
  • In the last few minutes of churning, add the toasted black walnuts and allow them to mix evenly.

Step 5: Freeze & Serve

  • Transfer the churned ice cream to an airtight container and smooth the top with a spatula.
  • Freeze for at least 2 hours to firm up before serving.
  • Scoop and enjoy your homemade black walnut ice cream!

Notes

  • No Ice Cream Maker? You can make a no-churn version by whipping 2 cups of heavy cream until soft peaks form, then folding it into 1 can of sweetened condensed milk along with the black walnuts. Freeze for 6 hours before serving.
  • Nut Allergies? Substitute pecans or regular walnuts for a milder flavor.
  • Storage Tip: Store in an airtight container in the freezer for up to 2 weeks to maintain freshness.
