Black Pistachio: Choc Mousse & Blackberry Heart

Black Pistachio 🍫💚 — Choc Mousse & Blackberry Heart

Few desserts balance earthy pistachio, intense chocolate, and vibrant berry quite like this showstopper from Ronny Latua. Black Pistachio is a modern French entremet built on texture contrast and flavour harmony: a nutty almond–pistachio base, a glossy dark-chocolate mousse, and a hidden blackberry–yoghurt panna cotta that delivers an unexpected brightness with every bite.

Each slice reveals layers of colour and contrast — black, green, purple — a visual and sensory symphony that tastes as elegant as it looks. ✨

The Concept 🌰🍇🍫

At its heart, this dessert celebrates the dialogue between bitterness and fruitiness. The dark chocolate mousse, aerated with pâte à bombe, carries a silky, almost truffle-like texture, while the frozen panna cotta insert melts slowly into the mousse, balancing the richness. The pistachio-almond base adds subtle chew and nutty warmth, creating the perfect stage for the layers above.

Once assembled and frozen, the cake is sprayed with a velvet chocolate coating — a professional finish that transforms a simple mousse cake into patisserie art. Decorate with glossy pistachios and ripe blackberries, and you’ll have a centrepiece worthy of any occasion. 🎂

Key Elements to Master 🔑

• Pistachio Base: Moist and nutty, lightened by a meringue fold. Use pure pistachio paste — not sweetened — for natural green hues and rich aroma.
• Blackberry–Yoghurt Panna Cotta: A cool, tangy heart that refreshes the palate. Freeze it completely before inserting.
• Dark Chocolate Mousse: Built on a pâte à bombe base for exceptional stability and lightness. Choose high-quality 70–72% chocolate.
• Velvet Spray Finish: A blend of cocoa butter and chocolate sprayed at 45–48°C on a cake at −18°C for that iconic suede effect.

Tips from the Pastry Lab 🧑‍🍳

💡 Freeze Deeply: The panna cotta insert should be rock-solid before unmoulding — it ensures clean layers.
💡 Temperature is Everything: Spray only when the cake is ice-cold and the spray is perfectly fluid.
💡 Soft Peaks Only: Overwhipped cream ruins mousse texture — aim for glossy, soft peaks that fold easily.
💡 Contrast Counts: The blackberry’s acidity is the soul of this dessert; don’t skip it.

Tasting Notes 🍴

When served at around 10°C, the chocolate softens, the panna cotta glides into the mousse, and the pistachio base releases its nutty perfume. Every forkful moves through crisp, creamy, fruity, and nutty textures — the very essence of fine patisserie.

Perfect for celebrations, this cake is as technically impressive as it is emotionally satisfying — rich yet refreshing, complex yet balanced.

Make It Ahead ⏰

You can assemble and freeze the entremet up to two weeks in advance. Spray and garnish on the serving day, then thaw slowly in the fridge. The result? A flawless, mirror-smooth texture under the velvet finish — guaranteed to impress your guests.
