Cooking Instructions

Step 1: Prepare the Chocolate Ganache

Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Let it sit for 1 minute, then stir slowly until the mixture turns smooth and glossy. Spoon the ganache into 6 small serving glasses, filling each about one quarter full.

Step 2: Make the Pistachio Paste

In a food processor, combine pistachios, sugar, vanilla extract, and a pinch of salt. Blend until the mixture becomes finely ground and slightly creamy. Scrape the sides as needed to ensure even blending.

Step 3: Whip the Cream and Mascarpone

In a mixing bowl, whip the cold heavy cream with a hand mixer until soft peaks form. Gently fold the mascarpone into the whipped cream using a spatula, being careful not to deflate the mixture.

Step 4: Combine and Fold

Add the pistachio paste into the cream mixture. Fold gently until everything is evenly combined and the mousse becomes pale green and airy. Taste and adjust sweetness if desired.

Step 5: Assemble the Dessert

Remove the chilled glasses with ganache from the refrigerator. Spoon the pistachio mousse over the firm ganache layer, filling each glass nearly to the top. Smooth the surface with the back of a spoon.

Step 6: Chill and Garnish

Refrigerate the glasses for 2–3 hours or until the mousse is fully set and slightly firm to the touch. Before serving, top with chopped roasted pistachios, chocolate curls, or a light sprinkle of edible gold dust for an elegant finish.

Mistakes to Avoid & Solutions

Mistake 1: Overheating the cream for ganache.
Solution: Heat until just simmering. Boiling cream can cause the chocolate to seize.

Mistake 2: Over whipping the cream.
Solution: Stop when soft peaks form; over-whipped cream turns grainy and affects texture.

Mistake 3: Not blending pistachios long enough.
Solution: Blend until creamy; a coarse mixture will make the mousse gritty.

Mistake 4: Mixing too aggressively.
Solution: Use gentle folding motions to keep the mousse airy.

Mistake 5: Skipping chill time.
Solution: Chill at least 2 hours so the mousse sets properly and flavors meld.

Storage and Reheating Tips

Store in the refrigerator, covered, for up to 3 days.
