Eid Table Showstopper Mastic Mousse Tower with Berry Coulis

Steps

1. 1

   Bloom gelatin and soften mastic

   • Pour the 3 tablespoons (45 ml) of cold milk into a small bowl and sprinkle the gelatin evenly over it.
   • Let sit for 5 minutes to bloom.
   • While the gelatin blooms, crush the mastic resin tears with the 1 tablespoon (12 g) of granulated sugar in a mortar and pestle or the bottom of a heavy pot until the mastic becomes a fine, sandy powder.
   • The sugar helps break down the resin; it will still be slightly grainy, and that is correct.

   Ready when: Gelatin appears opaque and spongy; mastic is a fine powder mixed with sugar crystals

   Tip: Do not try to grind mastic until perfectly smooth—some texture is natural and adds to the mouthfeel. Do not use hot water to dissolve gelatin at this stage; we'll bloom it first for better texture.

2. 2

   Prepare berry coulis

   • In a small saucepan, combine the 1.5 cups (225 g) of thawed frozen berries, 0.33 cup (65 g) of sugar, lemon juice, and 2 tablespoons (30 ml) of water.
   • Bring to a gentle simmer over medium heat, stirring occasionally, for 5 minutes.
   • In a small cup, stir the 0.75 teaspoon (2.5 g) of cornstarch with 1 tablespoon (15 ml) of cold water until smooth.
   • Pour the cornstarch slurry into the simmering berries and stir constantly for 1–2 minutes until the coulis thickens and becomes glossy and translucent.
   • It should coat the back of a spoon.
   • Remove from heat and let cool to room temperature, then strain through a fine-mesh sieve to remove seeds if desired (optional but creates an elegant finish).
   • The coulis can be made up to 2 days ahead and refrigerated.

   Ready when: Coulis coats the back of a spoon and is no longer cloudy; seeds are strained out if desired

   Tip: If your berries are very tart, you can add an extra teaspoon of sugar. The coulis thickens as it cools, so don't over-reduce it on the stove.

3. 3

   Whip the mastic cream

   • In your chilled metal bowl, pour the 1.25 cups (300 ml) of cold heavy cream.
   • Using an electric mixer or whisk by hand, whip on medium-high speed until the cream begins to hold soft peaks, about 3–4 minutes.
   • Gently fold in the powdered mastic mixture with a silicone spatula using broad, sweeping strokes—do not overmix.
   • The cream should remain light and airy; fold until the mastic is evenly distributed and the cream holds medium peaks (slightly firmer than soft peaks but not fully stiff).

   Ready when: Cream holds medium peaks and is flecked throughout with mastic; no large lumps of mastic remain

   Tip: Do not over-whip or the cream will become grainy. If you whip it too much, the mastic flavor becomes bitter and the texture separates slightly. Stop as soon as you see medium peaks.

4. 4

   Dissolve gelatin into mousse

   • Set the bloomed gelatin and milk over a pot of gently simmering water (a double boiler or makeshift setup with a heatproof bowl over a pot of steaming water) for 1–2 minutes, stirring gently, until the gelatin is completely dissolved and the mixture is warm to the touch (around 110°F / 43°C if using a thermometer).
   • Do not let it get hot or boil.
   • Remove from heat and let cool for 2 minutes.
   • Pour the warm gelatin mixture into the whipped mastic cream in a thin stream while folding gently and continuously with the silicone spatula.
   • Fold until no streaks of gelatin liquid remain and the mousse is homogeneous, smooth, and mousse-like.

   Ready when: Gelatin is fully dissolved (no graininess when touched to lip); mousse is uniform and holds soft peaks when a spoon is lifted

   Tip: If the gelatin has begun to set and looks lumpy when you add it, return it to the double boiler for a few more seconds. If the mousse looks like it might set too firmly, work quickly. You want the mousse to be pourable but hold its shape as it chills.

5. 5

   Line and fill tower base

   • Line a 4-inch (10 cm) round springform pan with two overlapping sheets of plastic wrap, pressing it into the corners and allowing excess to overhang the sides.
   • Pour the mastic mousse into the prepared pan and smooth the top with a silicone spatula.
   • Refrigerate for 30 minutes to set to a firm but not hard texture—the mousse should hold its shape when unmolded but still be creamy inside.

   Ready when: Mousse is set but jiggles slightly when pan is gently tapped; a finger pressed on top springs back slowly

   Tip: Don't fully refrigerate until the mousse is set; you want it to hold the yogurt layer on top. If it gets too firm, it will crack when the next layer is added and slightly compressed.

6. 6

   Prepare yogurt cream layer

   • In a clean, cold bowl, whisk together the 0.75 cup (180 g) of cold Greek yogurt, 2 tablespoons (25 g) of sugar, and 0.5 teaspoon (2.5 ml) of rose water if using.
   • Whisk gently until smooth and a pale, creamy consistency.
   • Do not overmix or the yogurt may become liquid.
   • The mixture should be thick but spreadable.

   Ready when: Yogurt is smooth, lump-free, and holds a ribbon when the whisk is lifted

   Tip: Rose water is optional but adds an authentic Middle Eastern floral note. Start with less than the recipe calls for and add more to taste, as rose water is potent and can easily overpower.

7. 7

   Layer yogurt cream on mousse

   • Remove the springform pan from the refrigerator.
   • Gently spread the yogurt cream evenly over the set mousse layer using a silicone spatula or the back of a spoon, creating a smooth, even layer.
   • Refrigerate again for 20 minutes to set the yogurt layer slightly, making it stable enough to support the berry topping.

   Ready when: Yogurt is no longer soft but still yields slightly when pressed; it maintains shape and doesn't slip when the pan is tilted gently

   Tip: If your kitchen is very warm, chill the yogurt mixture separately in the refrigerator for a few minutes before spreading to make it easier to work with.

8. 8

   Crown with fresh berries

   • Arrange the 1.5 cups (220 g) of fresh mixed berries (raspberries, blueberries, and halved strawberries) attractively on top of the yogurt layer, pressing them gently but firmly into the cream to anchor them.
   • You can create a spiral, concentric circle, or scattered pattern depending on your preference.
   • If desired, drizzle a little of the cooled berry coulis over the berries for added color and sheen.
   • Refrigerate the completed tower for at least 2 hours (or up to 4 hours) before serving.

   Ready when: All layers are firm and hold shape; berries are securely positioned and don't slide when the pan is gently tilted

   Tip: For maximum visual impact on a holiday table, use a mix of colorful berries and arrange them just before serving so they look fresh and glossy.

9. 9

   Unmold and serve

   • Run a warm, thin knife around the inside edge of the springform pan to loosen the mousse tower.
   • Gently unhinge and remove the springform ring.
   • Using the plastic wrap as a handle, carefully invert the tower onto a serving plate (optional—you can also serve it directly from the pan base for easier plating) or simply lift it onto the plate using the plastic wrap.
   • Peel away the plastic wrap carefully.
   • Place the tower in the center of a serving plate and pour or drizzle the berry coulis around the base in a decorative pool.
   • Serve chilled, slicing the tower into wedges with a sharp, hot knife (wipe between cuts for clean edges) or spooning portions onto dessert plates with a generous spoonful of coulis alongside.

   Ready when: Tower is released cleanly from the pan and holds its cylindrical shape; coulis pools elegantly on the plate

   Tip: If unmolding feels risky, it's perfectly fine to serve the tower directly from the springform pan base on the table—it looks elegant and there's no risk of collapse. Warm your knife under hot running water and wipe it dry between cuts to minimize tearing the layers.
