Ingredients
- Heavy Cream: 2 cups
- Pistachios (shelled, unsalted): 1 cup
- Granulated Sugar: 1/2 cup
- Egg Yolks: 4 large
- Vanilla Extract: 1 teaspoon
- Dark Chocolate (60-70% cacao): 4 ounces
- Unsalted Butter: 2 tablespoons
- Pinch of Salt: 1/4 teaspoon
Instructions
- Step 1: Prepare the pistachio paste. In a food processor, grind the pistachios with 1/4 cup of the sugar until a fine paste forms. Set aside.
- Step 2: Make the custard base. In a medium saucepan, whisk together the egg yolks and the remaining 1/4 cup sugar until pale and slightly thickened. Gradually whisk in 1 cup of the heavy cream.
- Step 3: Cook the custard. Cook the mixture over medium-low heat, stirring constantly with a spatula, until it thickens enough to coat the back of a spoon (about 5-7 minutes). Do not boil. Remove from heat and immediately whisk in the pistachio paste, vanilla extract, and salt.
- Step 4: Whip the remaining cream. In a separate bowl, whip the remaining 1 cup of heavy cream until stiff peaks form. Gently fold the whipped cream into the pistachio custard until smooth and uniform.
- Step 5: Make the chocolate ganache. Finely chop the dark chocolate and place it in a heatproof bowl. In a small saucepan, heat the butter over low heat until melted. Pour the melted butter over the chocolate and let it sit for 1 minute. Then, stir until smooth and glossy.
- Step 6: Assemble and chill. Divide the pistachio mousse among individual serving glasses or ramekins. Spoon a layer of chocolate ganache over each mousse. Cover and refrigerate for at least 2 hours, or preferably overnight, to allow the mousse to set.
Notes
- Store leftover mousse in the refrigerator for up to 3 days, but the ganache may lose some of its shine.
- This mousse is best served chilled, so avoid reheating to preserve its light and airy texture.
- Garnish with chopped pistachios and a sprinkle of sea salt right before serving for added flavor and visual appeal.
- For the smoothest ganache, ensure the butter is fully melted and hot enough to melt the chocolate evenly.
