A Michelin-level brunch dessert featuring vacuum-compressed caramelized banana layers stacked with espresso custard sheets, paired with tonka bean air, gold-leaf honeycomb shards, and aromatic banana essence.
Vacuum-compressing the banana before caramelizing it does two things a raw slice can't: it drives out air so the fruit holds a clean, stackable plank instead of collapsing into mush, and it lets the sugar coat penetrate evenly instead of just sitting on the surface. Tonka bean is the wildcard here — its vanilla-almond-cherry note behind the espresso custard is what keeps the whole stack from tasting like a simple banana split in disguise.

🍷Sommelier's Recommendation
Enhances the coffee bitterness and complements the dessert’s layered richness.
Deep caramel and raisin notes mirror the banana and honeycomb sweetness.
Steps:
- Prepare vacuum-compressed bananas: Slice bananas into thin planks and seal in a vacuum chamber at full pressure to intensify flavor and density. Rest 10 minutes.
- Caramelize banana layers: Heat sugar and glucose to 170°C (338°F). Add butter and salt, then coat banana slices. Lay flat and lightly torch for a glossy finish.
- Prepare espresso custard: Heat cream, milk, and espresso. Temper into egg yolks and sugar. Cook to 82°C (180°F), whisk in agar, and set in thin sheets. Chill and cut into precise layers.
- Create honeycomb: Cook sugar, honey, and water to 150°C (302°F). Remove from heat, whisk in baking soda, and pour onto a silicone mat. Cool, break into shards, and apply gold leaf.
- Prepare tonka bean air: Infuse warm milk with tonka bean, strain, and add lecithin. Use an ultrasonic homogenizer to generate a stable, fine foam.
- Optional banana crisp: Flash freeze thin banana slices in liquid nitrogen and shatter into delicate shards.
- Plating: Stack alternating banana and custard layers into a mille-feuille. Arrange honeycomb shards vertically. Spoon tonka air alongside. Garnish with cocoa nibs, espresso reduction, and micro mint. Finish with aromatic banana mist if available.
