Steps

Before you start

Read all steps and gather ingredients—gelatin blooming and multiple chilling stages require planning
Have ice water and a bowl ready for bloom gelatin
Bring cream and whole milk to room temperature before starting (about 1 hour ahead)
Prepare 6 individual serving glasses (5–6 oz each) and chill them

1
Bloom gelatin for panna cotta
- Pour 3 tablespoons (45 ml) of ice water into a small bowl.
- Sprinkle the 1.25 teaspoons (3.75 g) gelatin evenly over the water and let sit for 5 minutes without stirring.
- The gelatin will absorb the water and become spongy.
- Set aside.

Ready when: Gelatin is spongy and fully hydrated
Tip: Do not stir during blooming; it breaks down the gelatin structure.
2
Heat cream and milk baseOven 160°F / 70°C
- In a medium heavy-bottomed saucepan, combine 1.5 cups (360 ml) heavy cream, 0.75 cup (180 ml) whole milk, and 3 tablespoons (45 ml) honey.
- Heat over medium-high heat, stirring occasionally, until the mixture reaches 160°F (71°C) on a candy thermometer—this is when small bubbles begin forming at the edges and the surface shimmers.
- Do not boil.
+ Show details− Hide details
Ready when: Mixture reaches 160°F (71°C) with steam rising but no rolling boil
Tip: Use a candy thermometer for accuracy; overheating makes the panna cotta grainy.
3
Dissolve gelatin into cream
- Remove the saucepan from heat.
- Add the bloomed gelatin to the warm cream mixture and stir constantly for 2 minutes until fully dissolved and smooth.
- The residual heat will dissolve the gelatin completely.
- Stir in 0.5 teaspoon (2.5 ml) vanilla extract.
+ Show details− Hide details
Ready when: No gelatin particles visible; mixture is smooth and homogenous
Tip: Stir thoroughly to break up any clumps; lumps will remain in the final panna cotta.
4
Strain and cool panna cotta base
- Pour the mixture through a fine-mesh sieve into a large heatproof bowl, pressing gently with a spatula to remove any particles.
- Let cool to room temperature (about 10 minutes), stirring occasionally, then refrigerate for 20 minutes until the mixture reaches 45°F (7°C) and is just slightly thicker than heavy cream but still pourable.
+ Show details− Hide details
Ready when: Mixture coats the back of a spoon lightly and falls off slowly; pourable but thickened
Tip: Divide the cooled mixture evenly among chilled glasses (about 2.5 oz each) before refrigerating the first layer.
5
Pour and set panna cotta base layer
- Divide the cooled panna cotta mixture evenly among 6 chilled serving glasses (5–6 oz each), filling each to about 1.5 inches (4 cm) high.
- Transfer to the refrigerator and chill for 90 minutes until set but still slightly soft to the touch—the layer should no longer ripple when the glass is tilted gently.
+ Show details− Hide details
Ready when: Layer is set to the touch but still slightly yielding; no ripples when glass tilts
Tip: If the panna cotta is too thick when pouring, let it sit at room temperature for 2–3 minutes; if too runny, chill 5 more minutes.
6
Bloom gelatin for mousse
- While the panna cotta sets, pour 2.5 tablespoons (37.5 ml) of ice water into a small bowl.
- Sprinkle the 0.75 teaspoon (2.25 g) gelatin evenly over the water and let sit for 5 minutes without stirring until spongy.

Ready when: Gelatin is spongy and fully hydrated
7
Warm and dissolve mousse gelatinOven 150°F / 65°C
- Heat 2.5 tablespoons (37.5 ml) of milk in a small saucepan over medium heat until steaming (about 150°F / 66°C).
- Remove from heat and add the bloomed gelatin, stirring constantly for 1 minute until dissolved.
- Set aside to cool slightly (about 3 minutes) until lukewarm.
+ Show details− Hide details
Ready when: Gelatin is completely dissolved; mixture is smooth
Tip: The gelatin mixture must be lukewarm, not hot, when combined with the mousse base.
8
Mix pistachio mousse base
- In a large heatproof bowl, whisk together 0.75 cup (180 ml) room-temperature pistachio paste, 2 tablespoons (30 ml) honey, 0.5 teaspoon (2.5 ml) orange blossom water, and 1 teaspoon (3 g) finely grated orange zest until smooth and well combined.
- Pour in the lukewarm gelatin mixture and whisk vigorously for 1 minute until fully incorporated with no streaks.
+ Show details− Hide details
Ready when: Mixture is smooth, pale green, and homogenous with no visible gelatin threads
Tip: Room-temperature pistachio paste combines smoothly; cold paste will be lumpy.
9
Whip and fold cream into mousse
- In the bowl of an electric mixer fitted with the whisk attachment, whip 1 cup (240 ml) of cold heavy cream on medium-high speed for 2–3 minutes until soft peaks form—the cream should hold a gentle curve when the whisk is lifted.
- Using a spatula, fold the whipped cream into the pistachio mousse in three additions, being gentle to maintain airiness; fold until no white streaks remain and the mixture is light and airy throughout.
+ Show details− Hide details
Ready when: Mousse is pale green, fluffy, and holds soft peaks; no white streaks visible
Tip: Stop folding as soon as streaks disappear; overfolding deflates the mousse and ruins the texture.
10
Pipe or layer mousse onto panna cotta
- Remove the glasses from the refrigerator.
- Gently spoon or pipe the pistachio mousse evenly over the set panna cotta layer, filling each glass to about 3.5 inches (9 cm) high.
- Use about 1.5 oz mousse per glass.
- Return to the refrigerator and chill for 120 minutes until the mousse sets firmly but remains creamy.
+ Show details− Hide details
Ready when: Mousse is firm to the touch but still creamy; no jiggling when glass is tilted
Tip: If mousse becomes too thick to spoon, let it sit at room temperature for 5 minutes.
11
Make caramelized orange syrupOven 350°F / 175°C
- In a small saucepan, combine 0.75 cup (150 g) granulated sugar and 0.5 cup (120 ml) water.
- Heat over medium-high heat without stirring until the sugar dissolves, then continue heating until the syrup turns deep amber (about 350°F / 176°C on a candy thermometer), about 7–8 minutes.
- Remove from heat and immediately stir in 2 tablespoons (30 ml) honey and 0.25 teaspoon (1.25 ml) vanilla extract.
- Let cool for 2 minutes until bubbling subsides.
+ Show details− Hide details
Ready when: Syrup is deep amber and reaches 350°F (176°C); does not smell burnt
Tip: Do not stir while cooking; swirl the pan occasionally if needed. Stop immediately at deep amber to avoid bitter burnt flavor.
12
Cook orange slices until candied
- Slice 2 navel oranges into thin rings (about 0.2 inches / 5 mm thick), discarding seeds.
- Gently lay the slices in the still-warm caramel syrup, working in batches if needed to avoid crowding.
- Simmer over medium heat for 10–12 minutes, turning the slices halfway through, until the orange peel becomes translucent and slightly caramelized at the edges.
- The flesh should be tender and glossy.
- Transfer the slices to a parchment-lined plate using a slotted spoon and let cool for 15 minutes.
+ Show details− Hide details
Ready when: Orange peel is translucent and tender; flesh is soft and infused with syrup
Tip: Don't overcook or the oranges will become mushy and bitter. The syrup clings to the slices and hardens as they cool.
13
Assemble and garnish desserts
- Remove the glasses from the refrigerator.
- Top each panna cotta with one or two candied orange slices (cut in half if needed) and drizzle with 1 teaspoon (5 ml) of the remaining caramel syrup.
- Scatter 0.5–1 teaspoon (2–3 g) of roughly chopped roasted pistachios over the top of each glass.
- Serve immediately at chilled temperature or refrigerate up to 2 hours until serving.

Tips

The key to smooth, creamy panna cotta is not overheating the cream—aim for exactly 160°F (71°C) with a thermometer; this pasteurizes it gently without causing curdling or graininess.
Gelatin needs three distinct states: bloomed (hydrated), dissolved in warm liquid, and partially set before folding with other ingredients. Rushing this makes the texture grainy or rubbery.
The pistachio mousse must be at room temperature before folding in whipped cream; cold mousse resists folding and creates lumps.
Make the caramelized orange slices at least 2 hours ahead so the syrup sets and the flavors meld. Store them in an airtight container at room temperature and add to desserts just before serving.

Make ahead

Prepare the entire dessert up to 8 hours ahead. Refrigerate assembled glasses in an airtight container. Add candied orange slices and pistachio garnish just before serving to maintain their texture and appearance.

Storage & reheating

Refrigerator (covered): up to 3 days. The gelatin will continue to firm as it sits. Freezer: not recommended due to gelatin's texture changes upon thawing. Serve chilled directly from the refrigerator.

Substitutions

smooth natural pistachio paste, unsalted → almond butter or tahini (sesame paste). Use the same amount. Almond butter will be slightly milder and less floral; tahini adds nuttiness but omit the orange blossom water if using it. The color will be lighter or cream-colored rather than pale green.
orange blossom water → rose water (0.25 teaspoon / 1.25 ml) or omit. Rose water adds a floral note; if omitted, increase orange zest to 1.5 teaspoons (4.5 g) for brighter citrus flavor.
navel oranges → lemons or blood oranges. Lemons will be more tart; blood oranges will be sweeter with deeper color. Adjust sugar in the caramel syrup to taste.
unsalted roasted pistachios → crushed candied pistachios, toasted hazelnuts, or pomegranate arils. Each adds different texture and flavor. Pomegranate arils add tartness and brightness.
