Steps

Before you start

Strain labneh (if using yogurt, strain it through cheesecloth for 8–12 hours ahead to reach the thickness of sour cream)
Make sure labneh is at room temperature before folding into the mousse
Preheat oven to 350°F (175°C)
Have a 9-inch (23 cm) tart pan with a removable bottom ready

1
Make the almond crust
- Pulse almond flour, cold butter cubes, granulated sugar, and sea salt in a food processor until the mixture resembles coarse breadcrumbs (about 10–15 pulses).
- Press the mixture firmly into a 9-inch (23 cm) tart pan, covering the bottom and sides evenly with about ¼-inch (6 mm) thickness.
- Prick the bottom with a fork to prevent puffing.

Tip: Keep the butter very cold to create a tender crust; warm butter results in a greasy, dense texture.
2
Bake the crustOven 350°F / 175°C
- Place the tart pan on a baking sheet and bake at 350°F (175°C) for 12–15 minutes until the edges are light golden and the bottom is set but not browned.
- Remove from the oven and let cool on a wire rack for 10 minutes.

Ready when: Crust edges are pale golden and the bottom feels firm to the touch
Tip: Watch carefully—almond crusts brown quickly. If edges darken too much, tent loosely with foil.
3
Bloom the gelatin
- Pour 3 tablespoons (45 ml) cold water into a small bowl.
- Sprinkle gelatin powder over the water and let sit for 5 minutes without stirring, allowing the gelatin to absorb the water and form a spongy mass.
+ Show details− Hide details
Ready when: Gelatin is spongy and opaque, no dry granules visible
Tip: Do not skip blooming—it prevents lumps in the mousse.
4
Dissolve the gelatin
- Place the bloomed gelatin bowl over a small saucepan of gently simmering water (a bain-marie) for 1–2 minutes, stirring occasionally, until the gelatin is completely clear and liquid.
- Remove from heat and let cool to room temperature (about 2 minutes).
+ Show details− Hide details
Ready when: Gelatin is transparent, no opaque granules remain, and it coats the back of a spoon
Tip: Do not overheat gelatin; it will lose its gelling power. The bain-marie keeps it at a gentle, safe temperature.
5
Whip the cream
- In a large bowl, whip the 0.75 cup (180 ml) cold heavy cream with an electric mixer on medium-high speed for 2–3 minutes until soft peaks form (cream holds a shape but the tips curl over).
- Do not overbeat or the cream will become grainy.
+ Show details− Hide details
Ready when: Cream holds soft peaks that curl at the tips when the whisk is lifted
Tip: Stop beating as soon as soft peaks form—overbeating turns cream into butter.
6
Combine labneh and honey
- In a separate bowl, stir together the room-temperature labneh and 3 tablespoons (45 g) honey until smooth and well combined.
- Gently fold in the stripped thyme leaves.
+ Show details− Hide details
Ready when: Labneh and honey are uniform, thyme is evenly distributed
Tip: Do not overmix; you'll deflate any air trapped in the labneh. Stir gently.
7
Fold in the gelatin
- Pour the cooled dissolved gelatin into the labneh mixture in a thin stream while stirring gently with a whisk or rubber spatula.
- Mix until no streaks of gelatin remain and the mixture is smooth.

Ready when: Gelatin is fully incorporated, no transparent streaks visible
Tip: Stir the gelatin in slowly while folding to avoid lumps.
8
Build the mousse
- Using a rubber spatula, gently fold the whipped cream into the labneh mixture in two additions.
- Fold until no streaks of white cream remain and the mixture is light, airy, and uniform.
- Do not overfold or you will lose the airiness.
+ Show details− Hide details
Ready when: Mousse is pale, smooth, and has increased in volume by about one-third
Tip: Folding—not stirring—incorporates the cream while preserving air bubbles. Use a spatula and turn the bowl, not the spoon.
9
Fill the tart shell
- Pour the mousse into the cooled almond crust, spreading it evenly with a spatula.
- Smooth the top so it is level with the rim of the pan.
+ Show details− Hide details
Ready when: Mousse fills the tart evenly and the surface is smooth
Tip: Work quickly so the mousse does not begin to set before filling.
10
Chill the tart
- Cover the tart loosely with plastic wrap and refrigerate for at least 3 hours (or up to overnight) until the mousse is fully set and firm.
- You should see no jiggle when you gently shake the pan.
+ Show details− Hide details
Ready when: Mousse is completely firm; a gentle tap on the side shows no movement
Tip: Patience here prevents a soupy tart. If you're in a hurry, chill for at least 4 hours.
11
Make the pomegranate reduction
- Pour 0.5 cup (120 ml) pomegranate molasses and 2 tablespoons (30 g) honey into a medium saucepan.
- Bring to a gentle simmer over medium heat, stirring occasionally.
- Reduce heat to medium-low and simmer for 5–8 minutes until the mixture thickens slightly and becomes glossy.
- A wooden spoon dragged through it should leave a brief trail.
- Remove from heat and let cool for 5 minutes, then transfer to a small bowl to cool completely.
+ Show details− Hide details
Ready when: Reduction is thickened and glossy, and a spoon leaves a visible trail across the pan bottom
Tip: Watch for splattering; the reduction is hot and acidic. Keep a lid handy in case of vigorous bubbling.
12
Finish and serve
- Remove the tart from the refrigerator and gently remove it from the pan by pushing up on the removable bottom.
- Transfer to a serving platter.
- Spoon the cooled pomegranate reduction over the top of the mousse in concentric circles or a decorative pattern.
- Scatter the pomegranate arils over the reduction and garnish with fresh thyme sprigs if desired.
- Serve immediately, cutting with a warm knife (dipped in hot water and wiped dry between slices).

Ready when: Tart is removed from pan and garnished
Tip: A warm knife prevents the mousse from cracking or dragging. Wipe the blade after each cut.

Tips

Straining labneh ahead is essential for the best texture. If you use store-bought labneh that is already thick, you can skip the straining step, but bring it to room temperature before folding into the mousse.
The gelatin stabilizes the mousse and keeps it from separating; do not skip this ingredient or the filling will be watery after a day in the refrigerator.
The thyme should be fresh and vibrant; dried thyme will make the mousse taste musty and dull. Strip the leaves from tender sprigs just before using.
Pomegranate molasses is sold in Middle Eastern markets and online under various names (pomegranate concentrate, pomegranate syrup, pomegranate paste). It's not to be confused with pomegranate juice or grenadine.

Make ahead

The crust can be prepared and baked up to 2 days ahead; store in an airtight container at room temperature. The mousse can be made and chilled for up to 1 day ahead (cover tightly with plastic wrap to prevent it from absorbing refrigerator odors). The pomegranate reduction can be made up to 2 days ahead and stored in an airtight container in the refrigerator; warm gently over low heat before serving if it has solidified.

Storage & reheating

Store the finished tart in the refrigerator, covered loosely with plastic wrap, for up to 2 days. The tart does not freeze well due to the mousse's texture. To serve chilled tart, remove from the refrigerator 10 minutes before slicing to allow it to warm slightly and become more tender.

Substitutions

labneh (strained yogurt) → Greek yogurt (strained through cheesecloth for 6–8 hours) or sour cream thinned with 1 tablespoon of heavy cream. Greek yogurt will be slightly less tangy; sour cream will be more acidic and provide a sharper flavor.
pomegranate molasses → balsamic vinegar reduction (heat 1 cup balsamic vinegar until reduced to ¼ cup and thickened) mixed with 2 tablespoons honey. This creates a similar tart-sweet glaze but with a different flavor profile; the balsamic will be earthier.
fresh thyme sprigs → fresh mint leaves or a mix of thyme and mint. Mint will make the mousse brighter and more refreshing; use the same amount.
almond flour → ground pistachios or a 50/50 mix of almond and pistachio flour. Pistachios will add a subtle, nutty flavor and a slight greenish tint to the crust.
