Steps
Before you start
- Have heavy cream very cold (chill bowl and whisk if possible)
- Crush mastic crystals into a fine powder using a mortar and pestle or spice grinder
- Remove pomegranate seeds from the fruit just before serving so they stay juicy
- Ensure white chocolate is finely chopped so it melts evenly
Prepare mastic and chocolate
- Using a mortar and pestle or spice grinder, crush the mastic resin crystals into a fine powder (you should have about ½ teaspoon).
- Finely chop the white chocolate into pieces no larger than ¼ inch.

Ready when: Mastic is powdery and chocolate is in small, uniform pieces
Tip: Mastic resin is hard and can fly if not ground carefully; cover with a towel or grind in short bursts
Melt chocolate with mastic
- Set a heat-proof bowl over a pot of simmering water (the bowl should not touch the water).
- Add the chopped white chocolate and mastic powder to the bowl.
- Stir gently and constantly with a rubber spatula until the chocolate is completely melted and smooth, about 4–5 minutes.
- The mastic will blend evenly into the warm chocolate.

Ready when: Chocolate is completely melted, smooth, and no mastic particles are visible
Tip: Keep the water at a gentle simmer—if it boils, the steam will cause the chocolate to seize
Cool chocolate mixture
- Remove the bowl from the heat and let the chocolate cool to room temperature, stirring occasionally, about 10 minutes.
- It should be warm to the touch but no longer hot.

Ready when: Chocolate is warm but not hot; a clean finger can rest on it for a few seconds
Tip: Do not skip cooling or the hot chocolate will scramble the egg yolks
Whisk egg yolks and sugar
- In a large bowl, whisk together the egg yolks and sugar.
- Whisk steadily for 3–4 minutes until the mixture becomes pale, thick, and ribbon-like when the whisk is lifted.
- The volume should increase noticeably.

Ready when: Mixture is pale yellow, thick, and falls in ribbons from the whisk
Tip: Use room-temperature eggs for faster whisking; cold eggs take longer to aerate
Fold in chocolate
- Pour the cooled chocolate-mastic mixture into the egg yolk mixture.
- Using a rubber spatula, gently fold the chocolate into the eggs with about 12–15 strokes, just until no white streaks remain.
- Fold with a J-stroke: down the center, along the bottom, up the side, and over the top.

Ready when: No white streaks of egg remain; chocolate is evenly distributed
Tip: Overmixing will deflate the aerated eggs and make the mousse dense; fold gently and briefly
Whip heavy cream
- In a chilled bowl with a chilled whisk, whip the cold heavy cream and a pinch of salt to soft peaks.
- This should take 3–4 minutes.
- Stop when the cream forms billows that hold their shape but still look creamy—not yet stiff peaks.

Ready when: Cream forms soft peaks that curl over when the whisk is lifted
Tip: Do not overwhip or the cream will turn grainy and separate; stop at soft peaks
Fold in cream
- Gently fold the whipped cream into the chocolate-egg mixture in two additions.
- On the first fold, add half the cream and fold gently until just combined.
- Then fold in the remaining cream with 8–10 more strokes.

Ready when: Mousse is uniform and creamy; no white or brown streaks remain
Tip: Folding in cream in two stages helps preserve the mousse's airy texture
Chill mousse
- Divide the mousse evenly among six serving glasses or bowls (about ½ cup each).
- Smooth the tops with a small offset spatula.
- Cover loosely with plastic wrap and refrigerate for at least 3 hours, or until set and chilled through.

Ready when: Mousse is firm but still spoon-able, and very cold
Tip: Make the mousse up to 8 hours ahead and chill; add toppings just before serving
Finish and serve
- Just before serving, top each mousse with a generous scatter of fresh pomegranate seeds.
- Drizzle lightly with honey (about 1 teaspoon per serving).
- Serve chilled.

Ready when: Pomegranate seeds are scattered on top; honey glistens
Tip: Add pomegranate seeds and honey just before serving so the seeds stay juicy and fresh
Good to know
Tips
- Mastic resin is a precious ingredient; source it from specialty Middle Eastern, Mediterranean, or online gourmet grocers. A little goes a long way—its flavor is potent and beautiful.
- This mousse contains raw egg yolks. If you have concerns about raw eggs, pasteurize them in a 140°F (60°C) water bath for 3 minutes before whisking, then cool slightly before proceeding.
- For extra elegance, garnish with a small edible flower (like a pansy or viola) or a whisper of finely grated white chocolate alongside the pomegranate seeds.
- The key to a light mousse is proper aeration: don't skip the whisking of eggs and cream, and fold gently to preserve the air bubbles you've incorporated.
Make ahead
Prepare the mousse through step 7 (chilling) up to 8 hours ahead. Top with pomegranate seeds and honey just before serving.
Storage & reheating
Store covered in the refrigerator for up to 2 days. The mousse does not freeze well due to the whipped cream texture. Serve chilled; do not reheat.
Substitutions
- mastic resin crystals → ½ tsp ground cardamom or ¼ tsp ground pistachios powder mixed with a pinch of rosewater. Mastic has a unique piney-sweet flavor; cardamom is the closest substitute, though the flavor profile will be warmer and spicier rather than piney
- fresh pomegranate seeds (arils) → Fresh raspberries, blackberries, or candied pistachio pieces. Choose tart berries to balance the sweet mousse; avoid dark berries if you prefer visual contrast
- raw honey or floral honey → Pure maple syrup or date syrup (dibs). Date syrup complements the Middle Eastern profile; adjust quantity to taste as it is slightly less sweet
- white chocolate, finely chopped → 6 oz (170 g) milk chocolate. Milk chocolate will add a richer, less delicate flavor; the mousse will be slightly less sweet overall
